Description

剥離装置、シート処理装置、及び、剥離方法Peeling device, sheet processing device, and peeling method
 この発明は、剥離装置、シート処理装置、及び、剥離方法に関する。 The present invention relates to a peeling device, a sheet processing device, and a peeling method.
 例えば国際公開第2012/118032号公報に記載のように、多糖類シートは多糖類、香料、水を混合したスラリーを、幅方向に比べて長手方向が長いベースシート上に塗工して形成される。多糖類シートは、適宜の水分量に乾燥させた後、ベースシートから剥がされる。多糖類シートはベースシートから剥がされる剥離シート(機能シート)である。ベースシートから剥がされた剥離シートは、例えば適宜の大きさの多数の裁刻片に裁刻される。裁刻片は、たばこ或いはたばこ類似物に混合される。裁刻片は、たばこの燃焼、又は、たばこ類似品の加熱等によって香料を放出させる目的で使用する。 For example, as described in International Publication No. 2012/118032, a polysaccharide sheet is formed by applying a slurry in which polysaccharides, fragrances, and water are mixed onto a base sheet whose longitudinal direction is longer than the width direction. To. The polysaccharide sheet is dried to an appropriate amount of water and then peeled off from the base sheet. The polysaccharide sheet is a release sheet (functional sheet) that is peeled off from the base sheet. The peeling sheet peeled off from the base sheet is, for example, cut into a large number of cutting pieces of an appropriate size. The cut pieces are mixed with tobacco or tobacco analogs. The cut pieces are used for the purpose of releasing fragrance by burning tobacco or heating a tobacco-like product.
 裁刻片を作るための裁断装置は、適宜の長さがない不連続な剥離シートを用いると、その機構上、不連続な剥離シートの供給初期のカット時に不良品の生出が多い傾向がある。このため、剥離シートをできる限り長く連続したシート状で供給することが求められている。さらに、適宜の長さがない不連続な剥離シートを裁断装置に手作業でセットする必要があり、稼働効率/人件費を含めたコスト低減のためにも、長く連続した剥離シートが求められる。 If a discontinuous release sheet having an appropriate length is used as a cutting device for making a cutting piece, due to its mechanism, there is a tendency that defective products are often produced at the initial cutting of the discontinuous release sheet. .. Therefore, it is required to supply the release sheet in the form of a continuous sheet for as long as possible. Further, it is necessary to manually set a discontinuous release sheet having an appropriate length in the cutting device, and a long and continuous release sheet is required for cost reduction including operation efficiency / labor cost.
 多糖類シートには、補強材となるような材料が混合されていない。乾燥させた多糖類シートは、引張応力が小さい。そのためベースシートから多糖類シートを剥離させる際に、多糖類シートを引っ張ると、多糖類シートにクラックが生じやすい。 The polysaccharide sheet is not mixed with a material that can be used as a reinforcing material. The dried polysaccharide sheet has a small tensile stress. Therefore, if the polysaccharide sheet is pulled when the polysaccharide sheet is peeled off from the base sheet, cracks are likely to occur in the polysaccharide sheet.
 引張応力が小さい多糖類シート(剥離シート)が引っ張られると損傷しやすいため、それ自体に強い引張力をかけることなく、ベースシートから剥離させ、適宜の長さの連続した剥離シートを得ることが求められる。 Since a polysaccharide sheet (release sheet) having a small tensile stress is easily damaged when pulled, it can be peeled from the base sheet without applying a strong tensile force to itself to obtain a continuous release sheet of an appropriate length. Desired.
 本発明は、剥離シート(機能シート)をベースシートから連続して剥離可能で、適宜の長さの連続した剥離シートを得ることが可能な剥離装置、シート処理装置、及び、剥離方法を提供することを目的とする。 The present invention provides a peeling device, a sheet processing device, and a peeling method capable of continuously peeling a release sheet (functional sheet) from a base sheet and obtaining a continuous release sheet having an appropriate length. The purpose is.
 一態様において、剥離装置は、長手方向が長手方向に直交する幅方向に比べて長いベースシートの表面に、ベースシートよりも長手方向への引張応力が低く、ベースシートに対して剥離可能な剥離シートを形成したシート状部材のベースシートから、剥離シートを剥離可能である。剥離装置は、案内部と、支持部と、引張部とを有する。案内部は、シート状部材を第1の方向に案内する。支持部は、案内部に対して離間して配置され、シート状部材のベースシートの表面とは反対側の裏面を鉛直方向に支持する。引張部は、案内部に離間し、ベースシートをベースシートの第2の方向に引張可能である。引張部は、ベースシートを第2の方向に引っ張った状態でベースシートの裏面を支持部に摺動させるとともに、支持部で剥離シートをベースシートの第2の方向とは異なる第3の方向に進行させ、支持部でベースシートに対して剥離シートを剥離させる。 In one aspect, the peeling device peels the surface of the base sheet, which is longer in the longitudinal direction than the width direction orthogonal to the longitudinal direction, with a lower tensile stress in the longitudinal direction than the base sheet and can be peeled from the base sheet. The release sheet can be peeled off from the base sheet of the sheet-like member on which the sheet is formed. The peeling device has a guide portion, a support portion, and a tension portion. The guide portion guides the sheet-shaped member in the first direction. The support portion is arranged so as to be separated from the guide portion, and vertically supports the back surface of the sheet-like member opposite to the front surface of the base sheet. The tension portion is separated from the guide portion and can pull the base sheet in the second direction of the base sheet. In the tension portion, the back surface of the base sheet is slid to the support portion while the base sheet is pulled in the second direction, and the release sheet is moved to the third direction different from the second direction of the base sheet at the support portion. Proceed and peel the release sheet from the base sheet at the support portion.

The release sheet 520 is a functional sheet containing an appropriate component and having an appropriate function.
 シート状部材500のベースシート510は、長手方向(X軸方向)が長手方向に直交する幅方向(Y軸方向)に比べて長い。ベースシート510の幅方向の幅は一例として580mm又は620mm程度である。ベースシート510の長手方向の長さは、幅方向の幅(一例として580mm又は620mm)よりも長い。ベースシート510の長さは、一例として数メートル以上で、好ましくは数十m以上である。ベースシート510の長さは、例えば1000mから2000m程度である。ベースシート510の長さは、適宜に設定可能である。 The base sheet 510 of the sheet-shaped member 500 is longer than the width direction (Y-axis direction) in which the longitudinal direction (X-axis direction) is orthogonal to the longitudinal direction. The width of the base sheet 510 in the width direction is, for example, about 580 mm or 620 mm. The length of the base sheet 510 in the longitudinal direction is longer than the width in the width direction (580 mm or 620 mm as an example). The length of the base sheet 510 is, for example, several meters or more, preferably several tens of meters or more. The length of the base sheet 510 is, for example, about 1000 m to 2000 m. The length of the base sheet 510 can be set as appropriate.
 ベースシート510及び剥離シート520は、それぞれ適宜の厚さを有する。ベースシート510は例えば50μm以下の厚さであることが好適で、容易に曲げられる可撓性を有することが好適である。ベースシート510は厚さ方向に例えば180°曲げたときであっても、白化現象が生じず、破断しないことが好適である。 The base sheet 510 and the release sheet 520 each have an appropriate thickness. The base sheet 510 preferably has a thickness of, for example, 50 μm or less, and preferably has flexibility that can be easily bent. It is preferable that the base sheet 510 does not cause a whitening phenomenon and does not break even when bent by, for example, 180 ° in the thickness direction.
 剥離シート520はベースシート510の表面512及び裏面514のうち、一面のみにある。ベースシート510のうち、剥離シート520が形成された面を表面512とし、剥離シート520が存在しない面を裏面514とする。 The release sheet 520 is on only one of the front surface 512 and the back surface 514 of the base sheet 510. Of the base sheet 510, the surface on which the release sheet 520 is formed is referred to as the front surface 512, and the surface on which the release sheet 520 does not exist is referred to as the back surface 514.
 シート状部材500の剥離シート520はベースシート510に対して適宜の密着力で密着している。剥離シート520は、ベースシート510に対して剥離可能である。剥離シート520は、ベースシート510よりも長手方向への引張応力が低い。剥離シート520及びベースシート510が分離した状態で、長手方向に適宜の引張応力で引っ張ったとき、剥離シート520は容易にクラックが生じ、破断し得る。ベースシート510は、長手方向に剥離シート520と同じ引張応力で引っ張ったとき、クラック及び破断を生じず、引張方向に移動する。ベースシート510の破断強度は例えば250MPa程度である。剥離シート520の破断強度は、一例であるが、ベースシート510の破断強度の1/100以下である。 The release sheet 520 of the sheet-like member 500 is in close contact with the base sheet 510 with an appropriate adhesion force. The release sheet 520 can be peeled off from the base sheet 510. The release sheet 520 has a lower tensile stress in the longitudinal direction than the base sheet 510. When the release sheet 520 and the base sheet 510 are separated and pulled in the longitudinal direction with an appropriate tensile stress, the release sheet 520 can easily crack and break. When the base sheet 510 is pulled in the longitudinal direction with the same tensile stress as the release sheet 520, the base sheet 510 does not crack or break and moves in the tensile direction. The breaking strength of the base sheet 510 is, for example, about 250 MPa. The breaking strength of the release sheet 520 is, for example, 1/100 or less of the breaking strength of the base sheet 510.
 剥離シート520はベースシート510上に形成されるため、剥離シート520の長手方向の長さは、ベースシート510の長手方向の長さと同じかそれよりも短い。剥離シート520の幅方向の幅は、ベースシート510の幅方向の幅と同じか、それよりも短い。剥離シート520の厚さは適宜に設定可能である。剥離シート520の厚さは、40μm~130μmが適しており、好ましくは50μm~100μm以下、さらに好ましくは50μm~80μm以下が好適である。 Since the release sheet 520 is formed on the base sheet 510, the length of the release sheet 520 in the longitudinal direction is the same as or shorter than the length in the longitudinal direction of the base sheet 510. The width of the release sheet 520 in the width direction is the same as or shorter than the width of the base sheet 510 in the width direction. The thickness of the release sheet 520 can be set as appropriate. The thickness of the release sheet 520 is preferably 40 μm to 130 μm, preferably 50 μm to 100 μm or less, and more preferably 50 μm to 80 μm or less.
 ベースシート510の一例は、PET(ポリエチレンテレフタレート)シートである。ベースシート510は透明である。ベースシート510は無色であっても、有色であってもよい。 An example of the base sheet 510 is a PET (polyethylene terephthalate) sheet. The base sheet 510 is transparent. The base sheet 510 may be colorless or colored.
 剥離シート520の一例は、多糖類シートである。多糖類シートは多糖類、及び、水を混合したスラリーをPETベースシート510上に塗工する。ベースシート510上の多糖類シートは、熱風乾燥工程にて例えば水分量6%程度に乾燥される。多糖類シートには、一般的な紙類に使用されるような補強材となるような材料などが混合されていない。多糖類シートを長手方向に引っ張ったときにほとんど伸びを生じない。多糖類シートの引張強度はベースシート510に対してきわめて低い。このため、多糖類シートを引っ張ると、容易にクラック及び又は破断が生じる。 An example of the release sheet 520 is a polysaccharide sheet. As for the polysaccharide sheet, a slurry in which polysaccharides and water are mixed is applied onto the PET base sheet 510. The polysaccharide sheet on the base sheet 510 is dried to, for example, a water content of about 6% in a hot air drying step. The polysaccharide sheet is not mixed with a material that serves as a reinforcing material as used in general papers. Almost no elongation occurs when the polysaccharide sheet is pulled in the longitudinal direction. The tensile strength of the polysaccharide sheet is extremely low compared to the base sheet 510. Therefore, when the polysaccharide sheet is pulled, cracks and / or breaks easily occur.
 剥離シート520は、ベースシート510上にあるとき、ベースシート510の表面512に密着し、適宜の水分量が保たれる。ベースシート510は、剥離シート520の保護シートとして用いられる。剥離シート520がベースシート510上にあるとき、水分量が維持され、剥離シート520はベースシート510から剥離した状態よりもクラックが生じ難い。 When the release sheet 520 is on the base sheet 510, it adheres to the surface 512 of the base sheet 510, and an appropriate amount of water is maintained. The base sheet 510 is used as a protective sheet for the release sheet 520. When the release sheet 520 is on the base sheet 510, the amount of water is maintained, and the release sheet 520 is less likely to crack than in the state of being peeled from the base sheet 510.
 剥離シート520をベースシート510から剥離させたとき、剥離シート520は、ベースシート510の表面512に張り付いていた面の水分が奪われて乾燥が進み、張り付いていた面を内側にしてカールする。このとき、ベースシート510から剥離した剥離シート520は、重力によってはクラックが生じない又は生じ難い。ベースシート510から剥離した剥離シート520は、大気の温度及び湿度によるが、時間の経過とともに乾燥が進み、上側から下側に指で押圧するなど、外力が加えられると、クラックが生じやすくなる。 When the release sheet 520 is peeled from the base sheet 510, the release sheet 520 is deprived of moisture from the surface of the base sheet 510 that is stuck to the surface 512, and the drying proceeds. To do. At this time, the release sheet 520 peeled off from the base sheet 510 does not or is unlikely to crack due to gravity. The release sheet 520 peeled from the base sheet 510 is dried with the passage of time depending on the temperature and humidity of the atmosphere, and cracks are likely to occur when an external force such as pressing with a finger from the upper side to the lower side is applied.
 剥離シート520は、ベースシート510に張り付いた状態で、ロール状にされることは許容される。すなわち、シート状部材500がロール状にされることは許容される。剥離シート520は、ベースシート510から剥離された状態で、ロール状にされることは許容される。 It is permissible for the release sheet 520 to be rolled while being attached to the base sheet 510. That is, it is permissible for the sheet-like member 500 to be rolled. It is permissible for the release sheet 520 to be rolled in a state of being peeled from the base sheet 510.
 図1に示すように、シート状部材500は、ベースシート510の幅方向の端部近傍とともに、剥離シート520の幅方向の端部近傍が、剥離装置10で剥離される前に、カッタ600で切断されることが好適である。剥離シート520の幅方向の端部近傍を予め除去することにより、剥離シート520を裁刻したとき、剥離シート520の品質を均一化しやすい。カッタ600で剥離シート520を切断する場合、剥離シート520のみ切断してもよく、剥離シート520及びベースシート510の両方を切断してもよい。ここでは、剥離シート520及びベースシート510の両方を切断する例について説明する。 As shown in FIG. 1, the sheet-like member 500 is formed by a cutter 600 before the vicinity of the widthwise end of the base sheet 510 and the vicinity of the widthwise end of the release sheet 520 are peeled off by the peeling device 10. It is preferable to be cut. By removing the vicinity of the end portion in the width direction of the release sheet 520 in advance, when the release sheet 520 is stamped, the quality of the release sheet 520 can be easily made uniform. When cutting the release sheet 520 with the cutter 600, only the release sheet 520 may be cut, or both the release sheet 520 and the base sheet 510 may be cut. Here, an example of cutting both the release sheet 520 and the base sheet 510 will be described.
 図3Aに示すように、剥離装置10は、案内部(送り機構)12と、支持部14と、引張部16とを有する。 As shown in FIG. 3A, the peeling device 10 has a guide portion (feed mechanism) 12, a support portion 14, and a tension portion 16.
 案内部12は、ベースシート510を下側に剥離シート520を上側に配置したシート状部材500を所定の案内方向(第1の方向)D1に案内する。所定の案内方向D1は、一例としてX軸に沿う方向である。案内部12がシート状部材500を所定の案内方向D1に案内する場合、シート状部材500の幅方向(Y軸方向)の1対の端面は、長手方向(X軸方向)に平行な状態を維持する。 The guide portion 12 guides the sheet-like member 500 in which the base sheet 510 is arranged on the lower side and the release sheet 520 is arranged on the upper side in a predetermined guide direction (first direction) D1. The predetermined guide direction D1 is, for example, a direction along the X axis. When the guide portion 12 guides the sheet-shaped member 500 in the predetermined guide direction D1, the pair of end faces in the width direction (Y-axis direction) of the sheet-shaped member 500 are parallel to the longitudinal direction (X-axis direction). maintain.
 本実施形態に係る剥離装置10では、シート状部材500は、捻じれを抑制し、シート状部材500の端面は、適宜のZX平面に沿って移動することが好適である。 In the peeling device 10 according to the present embodiment, it is preferable that the sheet-shaped member 500 suppresses twisting and the end face of the sheet-shaped member 500 moves along an appropriate ZX plane.
 案内部12は、例えば第1のローラ22を有する。第1のローラ22の回転軸22aは、Y軸方向に平行に延びている。第1のローラ22のY軸方向に沿う幅は、シート状部材500の幅よりも大きい。 The guide unit 12 has, for example, a first roller 22. The rotation shaft 22a of the first roller 22 extends parallel to the Y-axis direction. The width of the first roller 22 along the Y-axis direction is larger than the width of the sheet-shaped member 500.
 第1のローラ22は、長尺のシート状部材500を支持部14に向けて案内する。第1のローラ22は従動ローラでもよく、モータ等により能動的に動かされるローラでも良い。案内部12は、第1のローラ22の代わりに、コンベヤ等の搬送路を用いてもよい。案内部12によるシート状部材500の案内速度(送り速度)は適宜に設定可能である。 The first roller 22 guides the long sheet-shaped member 500 toward the support portion 14. The first roller 22 may be a driven roller or a roller actively moved by a motor or the like. The guide portion 12 may use a transport path such as a conveyor instead of the first roller 22. The guide speed (feed speed) of the sheet-shaped member 500 by the guide portion 12 can be appropriately set.
 図3A中、第1のローラ22は、シート状部材500の上側に存在している。第1のローラ22は、シート状部材500の剥離シート520の上面を回転する。第1のローラ22は、剥離シート520に接触するが、剥離シート520にクラックを生じたり、破断するような負荷をかけずにシート状部材500を所定の案内方向D1に案内する。 In FIG. 3A, the first roller 22 exists on the upper side of the sheet-shaped member 500. The first roller 22 rotates the upper surface of the release sheet 520 of the sheet-like member 500. The first roller 22 comes into contact with the release sheet 520, but guides the sheet-like member 500 in the predetermined guide direction D1 without applying a load that causes the release sheet 520 to crack or break.
 第1のローラ22と支持部14との間には、走行中のシート状部材500の張力及びシート状部材500の走行ラインを検出し、これらを調整する公知の調整機構(蛇行調整部材)24がある。図3Aに示すように、一例として、調整機構24は、例えばシート状部材500の幅方向の端部を検出するセンサ部24aと、シート状部材500が載置された1対のガイドローラ24b1,24b2と、1対の従動ローラ24c1,24c2とを有する。調整機構24のガイドローラ24b1,24b2の上端は、例えばローラ22の下端よりも上側に配置される。シート状部材500のベースシート510の裏面514は、ガイドローラ24b1,24b2に当接している。
 センサ部24aの一例は、シート状部材500のベースシート510の表面512側から裏面514側に通す光、又は、ベースシート510の裏面514側から表面512側に通す光など、光学的にシート状部材500の幅方向の端部を検出する。センサ部24aの他の一例は、シート状部材500のベースシート510の表面512側から裏面514側に吐出させる空気、又は、ベースシート510の裏面514側から表面512側に吐出させる空気など、空気流束の空気圧信号を検出することで、シート状部材500の幅方向の端部を検出する。
 図3B及び図3Cには、ガイドローラ24b1,24b2を代表して符号24bを付したガイドローラを示す。図3B中に実線及び破線で示すように、ローラ24bの中心軸は、センサ部24aで検出されるシート状部材500の幅方向の端部の位置に応じて、Y軸に平行な状態に対して例えばXY平面で揺動する。図3C中に実線及び破線で示すように、ガイドローラ24bは、センサ部24aで検出されるシート状部材500の幅方向の端部の位置に応じて、例えばY軸に平行に動く。このため、調整機構24は、シート状部材500の幅方向の端部の位置(案内状態)を調整する。ガイドローラ24bの動作は、図3B又は図3Cに示す例に限られず、図3Bに示す例及び図3Cに示す例を組み合わせ、ガイドローラ24bの中心軸がXY平面で揺動しながら、Y軸に沿って移動してもよい。調整機構24は、支持部14の後述するエッジ34でのシート状部材500の両端部の弛みを取る。なお、図3A中には、1対(2つ)のガイドローラ24b1,24b2の例を示すが、ガイドローラは、1つであってもよく、3つであってもよい。複数のガイドローラ24b1,24b2を用いてシート状部材500の端部の位置を調整する場合、ガイドローラ24b1,24b2の一方のみを図3B及び/又は図3Cに示す例のように動かしてもよい。
A known adjusting mechanism (meandering adjusting member) 24 that detects the tension of the sheet-shaped member 500 and the traveling line of the sheet-shaped member 500 during traveling and adjusts them between the first roller 22 and the support portion 14. There is. As shown in FIG. 3A, as an example, the adjusting mechanism 24 includes, for example, a sensor unit 24a that detects an end portion of the sheet-shaped member 500 in the width direction, and a pair of guide rollers 24b1 on which the sheet-shaped member 500 is placed. It has 24b2 and a pair of driven rollers 24c1, 24c2. The upper ends of the guide rollers 24b1, 24b2 of the adjusting mechanism 24 are arranged above, for example, the lower ends of the rollers 22. The back surface 514 of the base sheet 510 of the sheet-like member 500 is in contact with the guide rollers 24b1, 24b2.
An example of the sensor unit 24a is optically sheet-like, such as light passing from the front surface 512 side to the back surface 514 side of the base sheet 510 of the sheet-like member 500, or light passing from the back surface 514 side to the front surface 512 side of the base sheet 510. The end portion of the member 500 in the width direction is detected. Another example of the sensor unit 24a is air such as air discharged from the front surface 512 side to the back surface 514 side of the base sheet 510 of the sheet-like member 500, or air discharged from the back surface 514 side to the front surface 512 side of the base sheet 510. By detecting the air pressure signal of the flux, the end portion of the sheet-like member 500 in the width direction is detected.
3B and 3C show guide rollers with reference numerals 24b on behalf of the guide rollers 24b1, 24b2. As shown by the solid line and the broken line in FIG. 3B, the central axis of the roller 24b is parallel to the Y axis according to the position of the end portion in the width direction of the sheet-like member 500 detected by the sensor unit 24a. For example, it swings on the XY plane. As shown by the solid line and the broken line in FIG. 3C, the guide roller 24b moves parallel to, for example, the Y axis according to the position of the end portion in the width direction of the sheet-shaped member 500 detected by the sensor unit 24a. Therefore, the adjusting mechanism 24 adjusts the position (guidance state) of the end portion of the sheet-shaped member 500 in the width direction. The operation of the guide roller 24b is not limited to the example shown in FIG. 3B or FIG. 3C, and the example shown in FIG. 3B and the example shown in FIG. You may move along. The adjusting mechanism 24 removes slack at both ends of the sheet-like member 500 at the edge 34 of the support portion 14, which will be described later. Although an example of a pair (two) of guide rollers 24b1, 24b2 is shown in FIG. 3A, the number of guide rollers may be one or three. When adjusting the position of the end portion of the sheet-like member 500 using a plurality of guide rollers 24b1, 24b2, only one of the guide rollers 24b1, 24b2 may be moved as in the example shown in FIGS. 3B and / or 3C. ..
 調整機構24で検知した信号に基づいて、シート状部材500にたるみや破断を生じた場合には、剥離装置10は、必要に応じて警告音を発し、及び/又は、動作を止める。 When the sheet-shaped member 500 is slackened or broken based on the signal detected by the adjusting mechanism 24, the peeling device 10 emits a warning sound as necessary and / or stops the operation.
 第1のローラ22は、シート状部材500の下側に存在していてもよい。第1のローラ22は、シート状部材500の上側及び下側の両方に存在していてもよい。 The first roller 22 may exist under the sheet-shaped member 500. The first roller 22 may be present on both the upper side and the lower side of the sheet-like member 500.
 支持部14は、案内部12のローラ22に対して離間している。支持部14は、案内部12の案内方向D1の下流側にある。図4に示すように、支持部14は、シート状部材500のベースシート510の剥離シート520が形成された表面512とは反対側の裏面514を、シート状部材500の所定の案内方向(X方向)に直交するY軸方向に適宜の幅で、下側から支持する。このため、支持部14は、ベースシート510の裏面514を鉛直方向(Z方向)に支持する。 The support portion 14 is separated from the roller 22 of the guide portion 12. The support portion 14 is on the downstream side of the guide portion 12 in the guide direction D1. As shown in FIG. 4, the support portion 14 has a back surface 514 on the side opposite to the front surface 512 on which the release sheet 520 of the base sheet 510 of the sheet-like member 500 is formed in a predetermined guide direction (X) of the sheet-like member 500. It is supported from below with an appropriate width in the Y-axis direction orthogonal to the direction). Therefore, the support portion 14 supports the back surface 514 of the base sheet 510 in the vertical direction (Z direction).
 支持部14は、X軸方向及びZ軸方向に比べて、Y軸方向に長いバー形状に形成されている。支持部14は、シート状部材500の幅よりも長く形成されている。支持部14のY軸方向の幅は、シート状部材500のY軸方向の幅よりも大きい。このため、支持部14は、シート状部材500のY軸方向の一端と他端との間(端面間)を連続的に支持する。 The support portion 14 is formed in a bar shape that is longer in the Y-axis direction than in the X-axis direction and the Z-axis direction. The support portion 14 is formed longer than the width of the sheet-shaped member 500. The width of the support portion 14 in the Y-axis direction is larger than the width of the sheet-like member 500 in the Y-axis direction. Therefore, the support portion 14 continuously supports between one end and the other end (between the end faces) of the sheet-shaped member 500 in the Y-axis direction.
 支持部14は、後述するように、引張部16でベースシート510へ付与される張力を受けた場合、支持部14の形状を維持し、永久変形(塑性変形)せず、かつ、連続的な変形力での不要な振動を生じない程度の剛性を有する。支持部14は、変形が抑制された金属材等で形成されている。支持部14は、一例としてステンレス鋼材で形成されている。 As will be described later, when the support portion 14 receives the tension applied to the base sheet 510 by the tension portion 16, the support portion 14 maintains the shape of the support portion 14, does not undergo permanent deformation (plastic deformation), and is continuous. It has enough rigidity to prevent unnecessary vibration due to deformation force. The support portion 14 is formed of a metal material or the like whose deformation is suppressed. The support portion 14 is made of stainless steel as an example.
 図4に示すように、支持部14は、支持面32と、エッジ(ベースシート510の裏面514を押さえた位置)34とを有する。支持部14は、さらに、底面36と、底面36と支持面32とを連続させる連続面38とを有する。支持部14は、Y軸方向側から見ると、略台形状に形成されている。 As shown in FIG. 4, the support portion 14 has a support surface 32 and an edge (position where the back surface 514 of the base sheet 510 is pressed) 34. The support portion 14 further has a bottom surface 36 and a continuous surface 38 that connects the bottom surface 36 and the support surface 32. The support portion 14 is formed in a substantially trapezoidal shape when viewed from the Y-axis direction side.
 底面36及び連続面38は、図4中では直交しているが、1つの連続した曲面であってもよい。 Although the bottom surface 36 and the continuous surface 38 are orthogonal to each other in FIG. 4, they may be one continuous curved surface.
 支持面32及びエッジ34は、ベースシート510の進行方向(例えばX軸方向)に直交する方向(Y軸方向)に延びている。支持面32及びエッジ34は連続している。支持面32は、本実施形態では、XY平面に平行な第1の支持面32aと、XY平面に対して傾斜する第2の支持面32bとを有する。第2の支持面32bは、X軸方向の下流に向かうにつれてZ軸方向の厚さを小さくするように傾斜している。なお、支持面32は、平面ではなく、X軸方向の上流側から下流側に向かって、曲面として、徐々にZ軸方向の厚さを薄くしていてもよい。支持面32は、平面と曲面との組み合わせであってもよい。 The support surface 32 and the edge 34 extend in a direction (Y-axis direction) orthogonal to the traveling direction (for example, the X-axis direction) of the base sheet 510. The support surface 32 and the edge 34 are continuous. In the present embodiment, the support surface 32 has a first support surface 32a parallel to the XY plane and a second support surface 32b inclined with respect to the XY plane. The second support surface 32b is inclined so as to reduce the thickness in the Z-axis direction toward the downstream in the X-axis direction. The support surface 32 may be formed as a curved surface from the upstream side to the downstream side in the X-axis direction instead of a flat surface, and the thickness in the Z-axis direction may be gradually reduced. The support surface 32 may be a combination of a flat surface and a curved surface.
 エッジ34は、YZ平面に平行な面として形成されている。エッジ34の高さは例えば1mm程度である。エッジ34のうち、第2の支持面32bに連続する上端に符号34aを付し、底面36に連続する下端に符号34bを付す。 The edge 34 is formed as a plane parallel to the YZ plane. The height of the edge 34 is, for example, about 1 mm. Of the edges 34, a reference numeral 34a is attached to the upper end continuous with the second support surface 32b, and a reference numeral 34b is attached to the lower end continuous with the bottom surface 36.
 エッジ34は、Y軸に沿って長い直線状、微小面取り、又は、微小R形状の仕上げとする。エッジ34は、鋭利にせず、エッジ34にベースシート510を押し当てながら摺動させたときにベースシート510が切断しないようにする。 The edge 34 has a long straight line, a minute chamfer, or a minute R shape finish along the Y axis. The edge 34 is not sharpened so that the base sheet 510 is not cut when the base sheet 510 is slid while being pressed against the edge 34.
 支持部14は固定されていてもよいし、所定の範囲内を可動可能であってもよい。本実施形態では、支持部14が可動可能である。図3Aに示すように、支持部14は、Y軸方向に延びた中心軸(回転軸)42aの軸回りに回動可能なアーム42の先端に支持されている。支持部14は、シート状部材500のベースシート510の引張力に基づいて、中心軸42aの軸回りに移動可能である。アーム42の近傍には、アーム42の回動量を規定するストッパ44が固定されている。このため、支持部14は、所定の範囲内を移動可能である。 The support portion 14 may be fixed or may be movable within a predetermined range. In this embodiment, the support portion 14 is movable. As shown in FIG. 3A, the support portion 14 is supported by the tip of an arm 42 that can rotate around the central axis (rotational axis) 42a extending in the Y-axis direction. The support portion 14 can move around the central axis 42a based on the tensile force of the base sheet 510 of the sheet-like member 500. A stopper 44 that regulates the amount of rotation of the arm 42 is fixed in the vicinity of the arm 42. Therefore, the support portion 14 can move within a predetermined range.
 図4中、第1の支持面32aがXY平面に平行で、第2の支持面32bがXY平面に傾斜している例を示している。第1の支持面32aがXY平面に傾斜し、第2の支持面32bがXY平面に平行であってもよい。第1の支持面32a及び第2の支持面32bがそれぞれXY平面に傾斜していてもよい。 FIG. 4 shows an example in which the first support surface 32a is parallel to the XY plane and the second support surface 32b is inclined to the XY plane. The first support surface 32a may be inclined to the XY plane and the second support surface 32b may be parallel to the XY plane. The first support surface 32a and the second support surface 32b may be inclined in the XY plane, respectively.
 支持面32及びエッジ34には、ベースシート510の裏面514が押し付けられ、ベースシート510の裏面514を摺動可能である。 The back surface 514 of the base sheet 510 is pressed against the support surface 32 and the edge 34, and the back surface 514 of the base sheet 510 can be slidable.
 引張部16は、案内部12及び支持部14に対して離間している。支持部14と引張部16とは離間せず、隣接していてもよい。 The tension portion 16 is separated from the guide portion 12 and the support portion 14. The support portion 14 and the tension portion 16 may be adjacent to each other without being separated from each other.
 引張部16は、ベースシート510を所定の進行方向D2に引張可能である。引張部16は、案内部12で、シート状部材500のベースシート510及び剥離シート520を、案内部12の案内方向D1に、同じ速度で移動させる。なお、引張部16による張力は、ベースシート510にのみ負荷され、剥離シート520には負荷されない。 The tension portion 16 can pull the base sheet 510 in the predetermined traveling direction D2. The tension portion 16 is a guide portion 12 that moves the base sheet 510 and the release sheet 520 of the sheet-like member 500 in the guide direction D1 of the guide portion 12 at the same speed. The tension generated by the tension portion 16 is applied only to the base sheet 510 and not to the release sheet 520.
 引張部16は、ベースシート510を進行方向D2に引っ張った状態でベースシート510の裏面514を支持部14の支持面32及びエッジ34に摺動させる。引張部16は、支持部14でベースシート510の進行方向D2に対し、剥離シート520を異なる進行方向D3に進行させ、支持部14でベースシート510に対して剥離シート520を剥離させる。 The tension portion 16 slides the back surface 514 of the base sheet 510 on the support surface 32 and the edge 34 of the support portion 14 in a state where the base sheet 510 is pulled in the traveling direction D2. In the tension portion 16, the support portion 14 advances the release sheet 520 in a different travel direction D3 with respect to the traveling direction D2 of the base sheet 510, and the support portion 14 peels the release sheet 520 from the base sheet 510.
 ベースシート510は引張部16による適宜の張力によって、ベースシート510の裏面514を支持部14の支持面32及びエッジ34に密着させながら、摺動させた場合であっても、ベースシート510自体に白化現象が生じず、破断しない。 The base sheet 510 is attached to the base sheet 510 itself even when the back surface 514 of the base sheet 510 is slid while being in close contact with the support surface 32 and the edge 34 of the support portion 14 by an appropriate tension of the tension portion 16. Whitening phenomenon does not occur and it does not break.
 図4に示すように、引張部16は、シート状部材500の案内方向D1に対して、ベースシート510の進行方向D2を、支持部14で、鋭角αにする。鋭角αは0°よりも大きく、90°よりも小さい。鋭角αの下限角度は、支持部14の素材、厚さ等により調整される。図4中、ベースシート510の裏面514は、エッジ34の上端34aに接触するとともに、エッジ34の下端34bに接触している。ベースシート510の裏面514は、エッジ34の上端34aに接触するが、例えば鋭角αが上限角度90°に近い場合、エッジ34の下端34bには接触しない場合があり得る。 As shown in FIG. 4, the tension portion 16 sets the traveling direction D2 of the base sheet 510 with respect to the guiding direction D1 of the sheet-shaped member 500 at the support portion 14 at an acute angle α. The acute angle α is greater than 0 ° and less than 90 °. The lower limit angle of the acute angle α is adjusted by the material, thickness, and the like of the support portion 14. In FIG. 4, the back surface 514 of the base sheet 510 is in contact with the upper end 34a of the edge 34 and is in contact with the lower end 34b of the edge 34. The back surface 514 of the base sheet 510 contacts the upper end 34a of the edge 34, but may not contact the lower end 34b of the edge 34, for example, when the acute angle α is close to the upper limit angle 90 °.
 引張部16は、ベースシート510の進行方向D2と、剥離シート520の進行方向D3とのなす角度を、支持部14で、90°以上の角度βにする。 The tension portion 16 sets the angle formed by the traveling direction D2 of the base sheet 510 and the traveling direction D3 of the release sheet 520 at the support portion 14 at an angle β of 90 ° or more.
 引張部16は、ベースシート510を巻き取る巻取部(第1の巻取部)52と、巻取部52に向けてベースシート510を案内する第2のローラ54とを有する。 The tension portion 16 has a winding portion (first winding portion) 52 for winding the base sheet 510, and a second roller 54 for guiding the base sheet 510 toward the winding portion 52.
 巻取部52は、図示しないモータにより、Y軸方向に延びた中心軸52aの軸回りに回転可能である。巻取部52の回転軸(第1の中心軸)52aは、ベースシート510の進行方向D2に直交する。巻取部52のY軸方向に沿う幅は、シート状部材500の幅よりも大きい。巻取部52のモータは、ベースシート510及び剥離シート520を含むシート状部材500の速度及び張力を制御する。シート状部材500のベースシート510には、一定の張力がかけられ、一定の速度で動かされる。 The take-up portion 52 can be rotated around the axis of the central shaft 52a extending in the Y-axis direction by a motor (not shown). The rotation axis (first central axis) 52a of the winding portion 52 is orthogonal to the traveling direction D2 of the base sheet 510. The width of the winding portion 52 along the Y-axis direction is larger than the width of the sheet-shaped member 500. The motor of the winding unit 52 controls the speed and tension of the sheet-like member 500 including the base sheet 510 and the release sheet 520. A constant tension is applied to the base sheet 510 of the sheet-shaped member 500, and the base sheet 510 is moved at a constant speed.
 巻取部52は、巻き始めから巻き終わりに向けて巻取部52のベースシート510のロール516の半径rが次第に大きくなる。シート状部材500の案内速度を定速にする場合、巻取部52の回転速度が制御される。巻取部52は、巻取部52の巻き始めから巻き終わりの状態に向かうにつれて、巻取部52の回転速度が徐々に低下するように制御される。巻取部52は、巻取部52の巻き始めから巻き終わりの状態に向かうにつれて、巻取部52のトルクが徐々に大きくなるように制御される。 In the winding portion 52, the radius r of the roll 516 of the base sheet 510 of the winding portion 52 gradually increases from the beginning to the end of winding. When the guiding speed of the sheet-shaped member 500 is set to a constant speed, the rotation speed of the winding unit 52 is controlled. The winding unit 52 is controlled so that the rotation speed of the winding unit 52 gradually decreases from the winding start to the winding end state of the winding unit 52. The take-up unit 52 is controlled so that the torque of the take-up unit 52 gradually increases from the start to the end of the winding of the take-up unit 52.
 巻取部52のモータには、回転速度を低下させるのにしたがってトルクを上げる、例えばトルクモータを用いる。巻取部52のモータには、トルクモータの他、モータに流す電流を制限し、モータの発生トルクを抑制する機能を有するモータを用いることができる。このようなモータを用いることで、モータの回転速度を調整し、トルクを調整し、ベースシート510に一定の張力を維持しながら、一定の速度で案内して巻取部52で巻き取ることができる。 For the motor of the take-up unit 52, for example, a torque motor is used in which the torque is increased as the rotation speed is decreased. As the motor of the take-up unit 52, in addition to the torque motor, a motor having a function of limiting the current flowing through the motor and suppressing the torque generated by the motor can be used. By using such a motor, the rotation speed of the motor can be adjusted, the torque can be adjusted, and the base sheet 510 can be guided at a constant speed and wound by the winding unit 52 while maintaining a constant tension. it can.
 第2のローラ54の回転軸54aは、Y軸方向に平行に延びている。第2のローラ54のY軸方向に沿う幅は、シート状部材500の幅よりも大きい。第2のローラ54は、支持部14の支持面32及びエッジ34に摺動させたベースシート510を巻取部52に向けて案内する。第2のローラ54の中心軸54aは、固定されていてもよく、ベースシート510の張力に応じて所定の範囲内を可動可能であってもよい。第2のローラ54は、ベースシート510の張力を調整するダンサーローラであってもよい。この場合、巻取部52に案内するベースシート510の張力を一定又は略一定にすることができる。 The rotation shaft 54a of the second roller 54 extends parallel to the Y-axis direction. The width of the second roller 54 along the Y-axis direction is larger than the width of the sheet-shaped member 500. The second roller 54 guides the base sheet 510 slid on the support surface 32 and the edge 34 of the support portion 14 toward the take-up portion 52. The central shaft 54a of the second roller 54 may be fixed or may be movable within a predetermined range according to the tension of the base sheet 510. The second roller 54 may be a dancer roller that adjusts the tension of the base sheet 510. In this case, the tension of the base sheet 510 guided to the winding unit 52 can be made constant or substantially constant.
 第2のローラ54は従動ローラでもよく、モータ等により能動的に動かされるローラでもよい。第2のローラ54は必ずしも必要というわけではない。 The second roller 54 may be a driven roller or a roller actively moved by a motor or the like. The second roller 54 is not always necessary.
 例えば支持部14と第2のローラ54との間の位置には、ベースシート510上に剥離シート520が有るか否かを検知可能なセンサ26が配置されている。センサ26は、例えば透過式光電センサである。センサ26は、投光部26aと受光部26bとを有する。投光部26aは、例えばベースシート510の上方(裏面514に対向する側)に配置されている。受光部26bは例えばベースシート510の下方(表面512に対向する側)に配置されている。投光部26aから受光部26bに向かう光の交差軸は、ベースシート510の表面512及び裏面514と直交していてもよく、直交していなくてもよい。ベースシート510の上に剥離シート520が存在している場合に比べて、ベースシート510の上に剥離シート520が存在していない場合、投光部26aから受光部26bに向かう光の透光性が大きくなる。このため、センサ26は、ベースシート510の上に剥離シート520が存在しているか否かを検出可能である。なお、センサ26は、受光部26bの受光量を検出することで、ベースシート510の破断を検知可能である。 For example, at a position between the support portion 14 and the second roller 54, a sensor 26 capable of detecting whether or not the release sheet 520 is present on the base sheet 510 is arranged. The sensor 26 is, for example, a transmissive photoelectric sensor. The sensor 26 has a light emitting unit 26a and a light receiving unit 26b. The light projecting unit 26a is arranged above, for example, the base sheet 510 (the side facing the back surface 514). The light receiving portion 26b is arranged, for example, below the base sheet 510 (the side facing the surface 512). The crossing axis of the light from the light emitting unit 26a to the light receiving unit 26b may or may not be orthogonal to the front surface 512 and the back surface 514 of the base sheet 510. Compared with the case where the release sheet 520 is present on the base sheet 510, when the release sheet 520 is not present on the base sheet 510, the light transmittance from the light emitting portion 26a to the light receiving portion 26b is transmitted. Becomes larger. Therefore, the sensor 26 can detect whether or not the release sheet 520 is present on the base sheet 510. The sensor 26 can detect the breakage of the base sheet 510 by detecting the amount of light received by the light receiving unit 26b.

The lower surface 76a referred to here refers to the outer surface of the belt 76 in which the surface of the belt 76 of the upper belt conveyor 62 faces downward during traveling. All surfaces of the belt 76 can be a lower surface 76a. The width of the belt 76 along the Y-axis direction is larger than the width of the release sheet 520 of the sheet-like member 500. The length of the portion of the upper belt conveyor 62 that becomes the lower surface 76a of the belt 76 is shorter than the length along the longitudinal direction of the release sheet 520.
 下部ベルトコンベヤ64は、それぞれY軸方向に延設された1対のベルトローラ82,84と、1対のベルトローラ82,84に掛け回されて無端状に張られたベルト86とを有する。1対のベルトローラ82,84は図示しないモータにより動かされる。1対のベルトローラ82,84を1つのモータで動かしても、各ベルトローラ82,84をそれぞれ別のモータで動かしてもよい。下部ベルトコンベヤ64の1対のベルトローラ82,84は、上部ベルトコンベヤ62の1対のベルトローラ72,74と共通のモータにより動かされてもよい。下部ベルトコンベヤ64のベルト86は、その上面86aが第2の搬送方向に走行する。ここで言う上面86aとは、下部ベルトコンベヤ64のベルト86の表面が走行の途中で上方に向くベルト86の外側表面を指す。ベルト86の全ての表面が上面86aになり得る。ベルト86のY軸方向に沿う幅は、シート状部材500の下部ベルトコンベヤ64のベルト86の上面86aとなる部位の長さは、剥離シート520の長手方向に沿う長さに比べて短い。 The lower belt conveyor 64 has a pair of belt rollers 82 and 84 extending in the Y-axis direction, and a belt 86 hung around the pair of belt rollers 82 and 84 and stretched in an endless manner.

The upper surface 86a referred to here refers to the outer surface of the belt 86 whose surface of the belt 86 of the lower belt conveyor 64 faces upward during traveling. All surfaces of the belt 86 can be the top surface 86a. The width of the belt 86 along the Y-axis direction is shorter than the length of the portion of the lower belt conveyor 64 of the sheet-like member 500 that becomes the upper surface 86a of the belt 86 in the longitudinal direction of the release sheet 520.
 上部ベルトコンベヤ62の下面76aと、下部ベルトコンベヤ64の上面86aとは、対向している。上部ベルトコンベヤ62の下面76aと、下部ベルトコンベヤ64の上面86aとは、例えば数mmなど適宜の距離に近接した状態で離間するか、互いに圧力を負荷しない程度に接触する。上部ベルトコンベヤ62の下面76aと、下部ベルトコンベヤ64の上面86aとは、一部が接触し、一部が近接していてもよい。上部ベルトコンベヤ62の下面76a、及び、下部ベルトコンベヤ64の上面86aは、同一速度で同方向に移動する。上部ベルトコンベヤ62の下面76a、及び、下部ベルトコンベヤ64の上面86aの移動速度は、支持部14における剥離シート520の移動速度と同じか、剥離シート520の移動速度よりも僅かに速く設定されている。 The lower surface 76a of the upper belt conveyor 62 and the upper surface 86a of the lower belt conveyor 64 face each other.

The cut portion 90 is arranged on the downstream side of the transport portion 60 (the side opposite to the support portion 14). The cut portion 90 cuts the release sheet 520 to a predetermined size. The predetermined size is, for example, a rectangular shape of 1 mm × 3 mm. The width of the cut portion 90 along the Y-axis direction is larger than the width of the sheet-shaped member 500. The release sheet 520 is cut into a rectangular shape or an appropriate shape by the cut portion 90. That is, the shape of the release sheet 520 after cutting is not limited to a rectangular shape, and can be an appropriate shape.
 次に、この実施形態に係るシート処理装置8の作用について説明する。ここでは、ベースシート510及び剥離シート520が一緒に同一方向に移動する場合、シート状部材500の移動方向として符号D1を用いる。ベースシート510が剥離シート520と分離して移動する場合、ベースシート510の移動方向として符号D2を用いる。剥離シート520がベースシート510と分離して移動する場合、剥離シート520の移動方向として符号D3を用いる。 Next, the operation of the sheet processing device 8 according to this embodiment will be described. Here, when the base sheet 510 and the release sheet 520 move together in the same direction, the reference numeral D1 is used as the moving direction of the sheet-shaped member 500. When the base sheet 510 moves separately from the release sheet 520, the reference numeral D2 is used as the moving direction of the base sheet 510. When the release sheet 520 moves separately from the base sheet 510, the reference numeral D3 is used as the moving direction of the release sheet 520.
 シート処理装置8の剥離装置10に、シート状部材500をセットする。 The sheet-like member 500 is set in the peeling device 10 of the sheet processing device 8.
 図3Aに示すように、引張部16の巻取部52にベースシート510の先端を固定する。第2のローラ54にベースシート510の表面512を接触させる。支持部14の支持面32及びエッジ34にシート状部材500のベースシート510の裏面514を当接させる。 As shown in FIG. 3A, the tip of the base sheet 510 is fixed to the winding portion 52 of the tension portion 16. The surface 512 of the base sheet 510 is brought into contact with the second roller 54. The back surface 514 of the base sheet 510 of the sheet-like member 500 is brought into contact with the support surface 32 and the edge 34 of the support portion 14.
 案内部12には、シート状部材500の剥離シート520を上側に、ベースシート510を下側にして、シート状部材500を支持部14に向けて配置する。支持部14には、支持面32にシート状部材500のベースシート510の裏面514を載置する。引張部16のローラ54には、ベースシート510をかける。巻取部52には、ベースシート510の先端を固定する。巻取部52は、ベースシート510を例えば半周など、適宜の量、巻き取ってもよい。 The sheet-shaped member 500 is arranged on the guide portion 12 with the release sheet 520 of the sheet-shaped member 500 on the upper side and the base sheet 510 on the lower side toward the support portion 14. On the support portion 14, the back surface 514 of the base sheet 510 of the sheet-like member 500 is placed on the support surface 32. A base sheet 510 is applied to the roller 54 of the tension portion 16. The tip of the base sheet 510 is fixed to the take-up portion 52. The winding unit 52 may wind the base sheet 510 in an appropriate amount, for example, half a circumference.
 搬送部60の上部ベルトコンベヤ62のベルト76の下面76aと、下部ベルトコンベヤ64のベルト86の上面86aとの間には、ベースシート510に対して剥離させた剥離シート520を配置する。 A release sheet 520 peeled from the base sheet 510 is arranged between the lower surface 76a of the belt 76 of the upper belt conveyor 62 of the transport unit 60 and the upper surface 86a of the belt 86 of the lower belt conveyor 64.
 シート状部材500は、案内部12、支持部14及びローラ54での位置ずれが防止される状態に配置されている。 The sheet-shaped member 500 is arranged in a state in which misalignment between the guide portion 12, the support portion 14, and the roller 54 is prevented.
 この状態で、シート処理装置8を適宜に動作させる。 In this state, the sheet processing device 8 is operated appropriately.
 巻取部52は、回転により、ベースシート510を巻き取る。巻取部52の回転により、ベースシート510には適宜の張力が加えられる。このため、支持部14及び案内部12のシート状部材500のベースシート510にはシート状部材500の長手方向に沿って張力が加えられる。巻取部52の連続した回転により、例えば数十メートルの長さのベースシート510が徐々に巻取部52に巻き取られていく。巻取部52のロール516の半径rは次第に大きくなる。ベースシート510の移動速度は、ベースシート510と剥離シート520との密着力、移動方向D1,D2の間の角度等により適宜の範囲で調整される。 The take-up unit 52 winds up the base sheet 510 by rotating. An appropriate tension is applied to the base sheet 510 by the rotation of the take-up portion 52. Therefore, tension is applied to the base sheet 510 of the sheet-shaped member 500 of the support portion 14 and the guide portion 12 along the longitudinal direction of the sheet-shaped member 500. Due to the continuous rotation of the take-up portion 52, for example, the base sheet 510 having a length of several tens of meters is gradually taken up by the take-up portion 52. The radius r of the roll 516 of the take-up portion 52 gradually increases. The moving speed of the base sheet 510 is adjusted within an appropriate range depending on the adhesion between the base sheet 510 and the release sheet 520, the angle between the moving directions D1 and D2, and the like.
 案内部12は、第1のローラ22を用いるとともに、調整機構24によりシート状部材500の案内状態を調整しながら、シート状部材500の剥離シート520に負荷をかけずに、シート状部材500を所定の案内方向D1に案内する。調整機構24は、センサ部24aでシート状部材500に捻じれがあることを検知した場合、シート状部材500の捻じれを防止するように、ガイドローラ24b1,24b2等を動かす。シート状部材500が所定の案内方向D1に案内されるのに伴って、支持部14に対して案内部12の案内方向D1の上流側で、図1に示すように、カッタ600でシート状部材500(ベースシート510及び剥離シート520)の端部近傍を切断する。シート状部材500が案内部12及び支持部14に案内される場合、案内部12及び支持部14には、幅方向の両端が除去されたシート状部材500が案内される。 The guide portion 12 uses the first roller 22 and adjusts the guide state of the sheet-shaped member 500 by the adjusting mechanism 24, while not applying a load to the release sheet 520 of the sheet-shaped member 500, and the sheet-shaped member 500 is moved. The guide is guided in the predetermined guide direction D1. When the sensor unit 24a detects that the sheet-shaped member 500 is twisted, the adjusting mechanism 24 moves the guide rollers 24b1, 24b2 and the like so as to prevent the sheet-shaped member 500 from being twisted. As the sheet-shaped member 500 is guided in the predetermined guide direction D1, the sheet-shaped member is formed by the cutter 600 on the upstream side of the guide portion 12 in the guide direction D1 with respect to the support portion 14, as shown in FIG. The vicinity of the end portion of 500 (base sheet 510 and release sheet 520) is cut. When the sheet-shaped member 500 is guided to the guide portion 12 and the support portion 14, the sheet-shaped member 500 from which both ends in the width direction are removed is guided to the guide portion 12 and the support portion 14.
 調整機構24のセンサ部24aで検知される案内部12での、シート状部材500の捻じれが許容範囲内である場合、案内部12は、第1のローラ22により、シート状部材500に適宜の張力を維持した状態で、シート状部材500を案内方向D1に案内させ続ける。このため、シート状部材500のベースシート510の裏面514は、支持部14のうち上方に向けた支持面32に接触され続ける。 When the twist of the sheet-shaped member 500 in the guide portion 12 detected by the sensor portion 24a of the adjusting mechanism 24 is within the permissible range, the guide portion 12 is appropriately attached to the sheet-shaped member 500 by the first roller 22. The sheet-shaped member 500 is continuously guided in the guiding direction D1 while maintaining the tension of. Therefore, the back surface 514 of the base sheet 510 of the sheet-like member 500 continues to be in contact with the upward support surface 32 of the support portion 14.
 第2のローラ54を介して巻取部52でベースシート510を巻き取ると、ベースシート510は、張力を受ける。ベースシート510は、支持部14のエッジ34に対する上流側の移動方向D1から、支持部14のエッジ34で方向転換し、支持部14のエッジ34に対して下流側の移動方向D2に向けられる。引張部16は、シート状部材500のベースシート510の裏面514を、長手方向に沿って先端側から基端側まで、支持部14の支持面32及びエッジ34に押し付け続ける。このため、ベースシート510の裏面514がエッジ34に押し付けられた状態で、エッジ34には、ベースシート510の裏面514を摺動可能である。すなわち、シート状部材500のベースシート510の裏面514は、移動方向D1から移動方向D2に向かって移動しながら、支持部14の支持面32及びエッジ34に押し付けられた状態が維持される。 When the base sheet 510 is wound by the winding unit 52 via the second roller 54, the base sheet 510 receives tension. The base sheet 510 changes direction at the edge 34 of the support portion 14 from the movement direction D1 on the upstream side with respect to the edge 34 of the support portion 14, and is directed to the movement direction D2 on the downstream side with respect to the edge 34 of the support portion 14. The tension portion 16 continues to press the back surface 514 of the base sheet 510 of the sheet-like member 500 against the support surface 32 and the edge 34 of the support portion 14 from the tip end side to the base end side along the longitudinal direction. Therefore, the back surface 514 of the base sheet 510 can be slid on the edge 34 while the back surface 514 of the base sheet 510 is pressed against the edge 34. That is, the back surface 514 of the base sheet 510 of the sheet-like member 500 is maintained in a state of being pressed against the support surface 32 and the edge 34 of the support portion 14 while moving from the movement direction D1 toward the movement direction D2.
 ベースシート510は、支持部14の上流側(案内部12側)の案内方向D1に対して、支持部14のエッジ34で、支持部14の下流側(引張部16側)の進行方向D2が鋭角αにされている。剥離シート520の水分量は調整されている。シート状部材500の案内方向D1の移動速度が適宜の速度範囲である場合、剥離シート520はベースシート510との接着力でベースシート510の進行方向D2に向かう力を受ける。しかし、剥離シート520は、支持部14のエッジ34において、自身の曲げ難さ(剥離シート500をXY平面に真っ直ぐに保とうとする力)がベースシート510との間の接着力に勝り、ベースシート510から剥離する。このため、剥離シート520は、ベースシート510に対して、支持部14のエッジ34の上端34aの近傍で剥離する。剥離シート520は、移動方向D3に向かって移動する。このため、シート状部材500の剥離シート520は、支持部14のエッジ34に対する上流側の移動方向D1から、支持部14のエッジ34に対して下流側の移動方向D3に向けられる。ベースシート510の移動方向D2と、剥離シート520の移動方向D3とは、支持部14のエッジ34において、本実施形態では鈍角βである。 In the base sheet 510, the advancing direction D2 on the downstream side (pulling portion 16 side) of the supporting portion 14 is at the edge 34 of the supporting portion 14 with respect to the guiding direction D1 on the upstream side (guide portion 12 side) of the supporting portion 14. It has an acute angle α. The water content of the release sheet 520 is adjusted. When the moving speed of the guide direction D1 of the sheet-like member 500 is within an appropriate speed range, the release sheet 520 receives a force toward the traveling direction D2 of the base sheet 510 due to the adhesive force with the base sheet 510. However, the release sheet 520 has its own bending difficulty (the force to keep the release sheet 500 straight on the XY plane) at the edge 34 of the support portion 14 and is superior to the adhesive force between the release sheet 510 and the base sheet 510. Peel off from 510. Therefore, the release sheet 520 is peeled from the base sheet 510 in the vicinity of the upper end 34a of the edge 34 of the support portion 14. The release sheet 520 moves in the moving direction D3. Therefore, the release sheet 520 of the sheet-like member 500 is directed from the moving direction D1 on the upstream side with respect to the edge 34 of the support portion 14 to the moving direction D3 on the downstream side with respect to the edge 34 of the support portion 14. The moving direction D2 of the base sheet 510 and the moving direction D3 of the release sheet 520 are obtuse angles β in the present embodiment at the edge 34 of the support portion 14.
 なお、剥離シート520が所望の状態に対して高水分で軟質である場合、剥離シート520はベースシート510から剥離せず、案内方向D1から移動方向D2に向けられる可能性がある。このため、剥離シート520が所望の状態に対して高水分で軟質である場合、ベースシート510及び剥離シート520は、一緒に方向D2に向けられることがあり得る。 If the release sheet 520 is highly moist and soft with respect to the desired state, the release sheet 520 may not be peeled from the base sheet 510 and may be directed from the guiding direction D1 to the moving direction D2. Therefore, if the release sheet 520 is highly moist and soft with respect to the desired state, the base sheet 510 and the release sheet 520 may be oriented together in direction D2.
 ベースシート510に対する剥離シート520の剥離位置(支持部14のエッジ34の近傍)での剥離シート520の移動方向D3は、剥離位置でのシート状部材500の移動方向D1と同一である。剥離シート520は、搬送部60の上部ベルトコンベヤ62と下部ベルトコンベヤ64との間に入れられて搬送される。 The moving direction D3 of the peeling sheet 520 at the peeling position of the peeling sheet 520 with respect to the base sheet 510 (near the edge 34 of the support portion 14) is the same as the moving direction D1 of the sheet-like member 500 at the peeling position. The release sheet 520 is inserted between the upper belt conveyor 62 and the lower belt conveyor 64 of the conveying portion 60 and conveyed.
 上部ベルトコンベヤ62のベルト76の下面76a、及び、下部ベルトコンベヤ64のベルト86の上面86aの移動方向は、剥離シート520の移動方向D3を規定する。上部ベルトコンベヤ62のベルト76の下面76a、及び、下部ベルトコンベヤ64のベルト86の上面86aは、対向し、同一方向に同一速度で動く。上部ベルトコンベヤ62のベルト76の下面76a、及び、下部ベルトコンベヤ64のベルト86の上面86aの移動速度は、剥離シート520の移動速度と同じである。このため、支持部14と搬送部60との間で、剥離シート520に不要なたるみが生じるのが防止されている。 The moving direction of the lower surface 76a of the belt 76 of the upper belt conveyor 62 and the upper surface 86a of the belt 86 of the lower belt conveyor 64 defines the moving direction D3 of the release sheet 520. The lower surface 76a of the belt 76 of the upper belt conveyor 62 and the upper surface 86a of the belt 86 of the lower belt conveyor 64 face each other and move in the same direction at the same speed. The moving speeds of the lower surface 76a of the belt 76 of the upper belt conveyor 62 and the upper surface 86a of the belt 86 of the lower belt conveyor 64 are the same as the moving speed of the release sheet 520. Therefore, it is prevented that unnecessary slack is generated in the release sheet 520 between the support portion 14 and the transport portion 60.
 シート状部材500の案内方向D1への案内速度に対して、ベルト76,86による剥離シート520の進行方向D3の移動速度が速い場合、上部ベルトコンベヤ62のベルト76の下面76a、及び、下部ベルトコンベヤ64のベルト86の上面86aに対して剥離シート520が滑る。このとき、支持部14と搬送部60との間で、剥離シート520に不要なたるみが生じるのが防止されている。 When the moving speed of the release sheet 520 by the belts 76 and 86 in the traveling direction D3 is faster than the guiding speed of the sheet-shaped member 500 in the guiding direction D1, the lower surface 76a of the belt 76 of the upper belt conveyor 62 and the lower belt The release sheet 520 slides on the upper surface 86a of the belt 86 of the conveyor 64. At this time, it is prevented that unnecessary slack is generated in the release sheet 520 between the support portion 14 and the transport portion 60.
 シート状部材500の剥離シート520のうち、ベースシート510に密着している面の水分量は、外側に露出している表面に比べて多い。ベースシート510から剥離シート520が剥離した場合、剥離シート520のうちベースシート510に密着していた面は乾燥が進む。 Of the release sheet 520 of the sheet-like member 500, the amount of water on the surface in close contact with the base sheet 510 is larger than that on the surface exposed to the outside. When the release sheet 520 is peeled from the base sheet 510, the surface of the release sheet 520 that is in close contact with the base sheet 510 is dried.
 剥離シート520を上部ベルトコンベヤ62のベルト76の下面76aと下部ベルトコンベヤ64のベルト86の上面86aとの間に挟んだ状態で所定の方向D3に搬送する場合、支持部14に近接する下部ベルトコンベヤ64のベルト86の上面86aにより、剥離シート520うち、ベースシート510の表面512に密着していた面の乾燥が進み、ロール状に変形するのを防止する。 When the release sheet 520 is conveyed in the predetermined direction D3 while being sandwiched between the lower surface 76a of the belt 76 of the upper belt conveyor 62 and the upper surface 86a of the belt 86 of the lower belt conveyor 64, the lower belt close to the support portion 14 The upper surface 86a of the belt 86 of the conveyor 64 prevents the surface of the release sheet 520, which is in close contact with the surface 512 of the base sheet 510, from being dried and deformed into a roll shape.
 剥離シート520を上部ベルトコンベヤ62のベルト76の下面76aと下部ベルトコンベヤ64のベルト86の上面86aとの間に挟むと、剥離シート520うち、ベースシート510に密着していた面の乾燥により、剥離シート520がカールするのを防止する。 When the release sheet 520 is sandwiched between the lower surface 76a of the belt 76 of the upper belt conveyor 62 and the upper surface 86a of the belt 86 of the lower belt conveyor 64, the surface of the release sheet 520 that is in close contact with the base sheet 510 is dried. Prevents the release sheet 520 from curling.
 搬送部60の下流側のカット部(裁断装置)90は、剥離シート520を例えば所定の大きさのチップに切断する。適宜のカット部90を用いる場合、カット部90は、剥離シート520が例えば1mm×3mmの矩形状にカットし、コンテナ92に入れる。 The cutting portion (cutting device) 90 on the downstream side of the transport portion 60 cuts the release sheet 520 into, for example, chips having a predetermined size. When an appropriate cut portion 90 is used, the release sheet 520 cuts the cut portion 90 into a rectangular shape of, for example, 1 mm × 3 mm, and puts the cut portion 90 into the container 92.
 カット部90は、適宜の長さがない不連続な剥離シートを用いると、その機構上、不連続な剥離シートの供給初期のカット時に、不良品の生出が多い傾向がある。本実施形態では、剥離シート520をベースシート510の長さと略同一のできる限り長く連続したシート状でカット部90に供給することができる。このため、本実施形態に係る剥離装置10を含むシート処理装置8を用いることで、不良品の生出を抑制することができる。 If a discontinuous release sheet having an appropriate length is used for the cut portion 90, due to its mechanism, there is a tendency that defective products are often produced at the initial cutting of the discontinuous release sheet supply. In the present embodiment, the release sheet 520 can be supplied to the cut portion 90 in the form of a continuous sheet as long as possible, which is substantially the same as the length of the base sheet 510. Therefore, by using the sheet processing device 8 including the peeling device 10 according to the present embodiment, it is possible to suppress the production of defective products.
 さらに、剥離シート520が長く連続しているため、剥離シート520をカット部90に手作業でセットする作業を減らすことができる。このため、本実施形態に係る剥離装置10を含むシート処理装置8を用いることで、稼働効率/人件費を含めたコスト低減をすることができる。 Further, since the release sheet 520 is continuous for a long time, the work of manually setting the release sheet 520 on the cut portion 90 can be reduced. Therefore, by using the sheet processing device 8 including the peeling device 10 according to the present embodiment, it is possible to reduce the cost including the operating efficiency / labor cost.
 センサ26は、ベースシート510上に剥離シート520が存在しているか否かを検知する。センサ26がベースシート510上に剥離シート520が存在している場合、剥離装置10は、アラームを発する。ベースシート510の長さは予めわかっている。このため、シート処理装置8の図示しない制御部は、巻取部52でのベースシート510の積算巻取量によって、ベースシート510を巻き取り終えるまで巻取部52を動かし続ける。 The sensor 26 detects whether or not the release sheet 520 is present on the base sheet 510. When the sensor 26 has the release sheet 520 on the base sheet 510, the release device 10 issues an alarm. The length of the base sheet 510 is known in advance. Therefore, the control unit (not shown) of the sheet processing device 8 keeps moving the winding unit 52 until the base sheet 510 is completely wound by the integrated winding amount of the base sheet 510 in the winding unit 52.
 以上説明したように、本実施形態に係る剥離装置10を含むシート処理装置8は、以下のことが言える。 As described above, the sheet processing device 8 including the peeling device 10 according to the present embodiment can be said to be as follows.
 本実施形態に係る剥離装置10によれば、剥離シート(機能シート)520をベースシート510から長く連続して剥離可能で、適宜の長さの連続した剥離シート520を得ることが可能な剥離装置10、シート処理装置8、及び、剥離方法が提供される。剥離シート520の長さは、最長で、ベースシート510の長さと略同一である。 According to the peeling device 10 according to the present embodiment, the peeling sheet (functional sheet) 520 can be continuously peeled from the base sheet 510 for a long time, and a continuous peeling sheet 520 having an appropriate length can be obtained. 10. The sheet processing apparatus 8 and the peeling method are provided. The length of the release sheet 520 is the longest and is substantially the same as the length of the base sheet 510.
 剥離装置10は、シート状部材500の裏面514を支持部14に接触させた直後、ベースシート510の移動方向D2を支持部14のエッジ34で、鋭角αなど、大きく変え、剥離シート520の移動方向D3と別方向に送っている。このため、剥離装置10は、剥離シート520に触れず、ベースシート510に対して剥離シート520を剥離させることができる。このとき、剥離シート520自体に負荷をかけていない。このため、剥離装置10を用いることで、剥離シート520にクラック及び/又は破断が生じるのを抑制することができる。したがって、剥離シート520を連続した状態に得ることができる。 Immediately after the back surface 514 of the sheet-like member 500 is brought into contact with the support portion 14, the peeling device 10 significantly changes the moving direction D2 of the base sheet 510 at the edge 34 of the supporting portion 14, such as an acute angle α, and moves the peeling sheet 520. It is being sent in a direction different from the direction D3. Therefore, the peeling device 10 can peel the peeling sheet 520 against the base sheet 510 without touching the peeling sheet 520. At this time, no load is applied to the release sheet 520 itself. Therefore, by using the peeling device 10, it is possible to prevent cracks and / or breakage in the peeling sheet 520. Therefore, the release sheet 520 can be obtained in a continuous state.
 シート処理装置8は、搬送部60の上下のベルト76,86の間隙を調整することで、剥離シート520が乾燥によりカール状に変形することを抑制しながら、剥離シート520を所望の位置に搬送することができる。 The sheet processing device 8 transfers the release sheet 520 to a desired position while suppressing the release sheet 520 from being deformed into a curl shape due to drying by adjusting the gaps between the upper and lower belts 76 and 86 of the transfer unit 60. can do.
 シート処理装置8は、搬送部60の下流に配置したカット部90を用いて、剥離シート520を所望の大きさにカットすることができる。 The sheet processing device 8 can cut the release sheet 520 to a desired size by using the cutting portion 90 arranged downstream of the conveying portion 60.
 例えば剥離シート520が、多糖類、香料、水を混合したスラリーを、幅方向に比べて長手方向が長いベースシート510上に塗工して形成される、香料含有多糖類シートである、とする。剥離シート520が香料含有多糖類シートである場合、ベースシート510から剥がされた香料含有多糖類シートは、1mm×3mmの大きさの矩形片にカットされる。矩形片は、たばこ或いはたばこ類似物に混合される。矩形片は、たばこの燃焼、又は、たばこ類似品の加熱等によって香料を放出させる目的で使用する。 For example, it is assumed that the release sheet 520 is a fragrance-containing polysaccharide sheet formed by coating a slurry in which a polysaccharide, a fragrance, and water are mixed on a base sheet 510 whose longitudinal direction is longer than that in the width direction. .. When the release sheet 520 is a fragrance-containing polysaccharide sheet, the fragrance-containing polysaccharide sheet peeled from the base sheet 510 is cut into rectangular pieces having a size of 1 mm × 3 mm. The rectangular pieces are mixed with tobacco or tobacco analogs. The rectangular piece is used for the purpose of releasing a fragrance by burning tobacco or heating a tobacco-like product.
 上述したように、香料含有多糖類シートには、補強材となるような材料が混合されていない。乾燥させた香料含有多糖類シートは、引張応力が小さい。上述したシート処理装置8を用いると、シート処理装置8は、シート状部材500のベースシート510から香料含有多糖類シート(剥離シート)520を剥離させ、カット部90でのカットに至るまで、香料含有多糖類シート520に、香料含有多糖類シート520を破断させるような負荷をかけることを防止し、クラックの発生を防止している。このため、香料含有多糖類シート520が適切にカットされ、香料の含有率が所定の範囲内に維持された大量の矩形片が形成される。したがって、香料含有多糖類シート520の矩形片を含むたばこ又はたばこ類似品を製造する場合、各たばこ又はたばこ類似品の香料含有率を均一化することができる。 As mentioned above, the perfume-containing polysaccharide sheet is not mixed with a material that serves as a reinforcing material. The dried fragrance-containing polysaccharide sheet has a small tensile stress. When the above-mentioned sheet processing device 8 is used, the sheet processing device 8 peels the fragrance-containing polysaccharide sheet (release sheet) 520 from the base sheet 510 of the sheet-like member 500, and the fragrance is cut until the cut portion 90 cuts. It prevents the containing polysaccharide sheet 520 from being subjected to a load that breaks the fragrance-containing polysaccharide sheet 520, and prevents the occurrence of cracks. Therefore, the perfume-containing polysaccharide sheet 520 is appropriately cut to form a large amount of rectangular pieces in which the perfume content is maintained within a predetermined range. Therefore, when producing a tobacco or a tobacco-like product containing a rectangular piece of the flavor-containing polysaccharide sheet 520, the flavor content of each tobacco or the tobacco-like product can be made uniform.
 (第2実施形態)
 次に、第2実施形態について、図5から図7を用いて説明する。第2実施形態は第1実施形態の変形例である。ここでは、シート状部材500のベースシート510から剥離シート520を剥離させた直後に、剥離シート520をロール522として巻き取る例について説明する。
(Second Embodiment)
Next, the second embodiment will be described with reference to FIGS. 5 to 7. The second embodiment is a modification of the first embodiment. Here, an example will be described in which the release sheet 520 is wound up as a roll 522 immediately after the release sheet 520 is peeled from the base sheet 510 of the sheet-like member 500.
 図5に示すように、シート処理装置8の剥離装置210は、案内部212と、支持部14と、引張部216とを有する。剥離装置210は、案内部212、支持部14及び引張部216に加えて、剥離シート巻取部(第2の巻取部)218を有する。 As shown in FIG. 5, the peeling device 210 of the sheet processing device 8 has a guide portion 212, a support portion 14, and a tension portion 216. The peeling device 210 has a peeling sheet winding portion (second winding portion) 218 in addition to the guide portion 212, the support portion 14, and the tension portion 216.
 案内部212は、シート状部材500が巻かれた回転軸222aを有する巻出部222を有する。巻出部222のロール502は、例えば半径r0である。巻出部222の回転軸222aの回転中心はY軸に平行である。回転軸222aのY軸に沿う幅は、シート状部材500の幅よりも大きい。 The guide portion 212 has an unwinding portion 222 having a rotation shaft 222a around which the sheet-shaped member 500 is wound. The roll 502 of the unwinding portion 222 has, for example, a radius r0. The center of rotation of the rotation shaft 222a of the unwinding portion 222 is parallel to the Y axis. The width of the rotating shaft 222a along the Y axis is larger than the width of the sheet-shaped member 500.
 案内部212は、さらに、ニップローラ226と、ニップローラ226を駆動させるモータ228とを有する。 The guide unit 212 further includes a nip roller 226 and a motor 228 that drives the nip roller 226.
 図1に示すカッタ600は、例えば巻出部222とニップローラ226との間にある。カッタ600は、ニップローラ226と剥離シート巻取部218との間にあってもよい。 The cutter 600 shown in FIG. 1 is located between, for example, the unwinding portion 222 and the nip roller 226. The cutter 600 may be located between the nip roller 226 and the release sheet take-up portion 218.
 ニップローラ226の回転中心はY軸に平行である。ニップローラ226のY軸に沿う幅は、シート状部材500の幅よりも大きい。モータ228は、ニップローラ226を適宜に回転させる。ニップローラ226の回転速度によって、シート状部材500の案内方向D1への案内速度を規定する。ニップローラ226は例えば20m/min以下でシート状部材500を所定の案内方向(X軸方向)D1に案内する。モータ228は、シート状部材500の送り速度を定速に維持する。モータ228には、例えばサーボモータを使用し得る。 The center of rotation of the nip roller 226 is parallel to the Y axis. The width of the nip roller 226 along the Y axis is larger than the width of the sheet-shaped member 500. The motor 228 appropriately rotates the nip roller 226. The rotation speed of the nip roller 226 defines the guide speed of the sheet-shaped member 500 in the guide direction D1. The nip roller 226 guides the sheet-shaped member 500 in a predetermined guide direction (X-axis direction) D1 at, for example, 20 m / min or less. The motor 228 maintains the feed rate of the sheet-shaped member 500 at a constant speed. For the motor 228, for example, a servomotor may be used.
 巻出部222は、シート状部材500の張力に応じて従動回転する。巻出部222は、モータ228の駆動により、ニップローラ226でシート状部材500が案内方向D1に搬送されるのに伴って回転し、シート状部材500を案内方向D1に向けて送り出す。巻出部222によるシート状部材500が案内方向D1の案内速度は、モータ228及びニップローラ226により定速となる。巻出部222の回転速度は、シート状部材500が送り出されるのに伴って徐々に早くなる。 The unwinding portion 222 is driven to rotate according to the tension of the sheet-shaped member 500. The unwinding portion 222 rotates as the sheet-shaped member 500 is conveyed in the guide direction D1 by the nip roller 226 by driving the motor 228, and sends out the sheet-shaped member 500 in the guide direction D1. The guide speed of the sheet-shaped member 500 by the unwinding portion 222 in the guide direction D1 is set to a constant speed by the motor 228 and the nip roller 226. The rotation speed of the unwinding portion 222 gradually increases as the sheet-shaped member 500 is sent out.
 剥離シート巻取部218は、回転軸(第2の中心軸)218aがY軸方向に平行なドラム状である。巻取部218の回転軸218aは、ベースシート510の進行方向D2に直交する。回転軸218aのY軸に沿う幅は、シート状部材500の幅よりも大きい。 The release sheet winding unit 218 has a drum shape in which the rotation axis (second central axis) 218a is parallel to the Y-axis direction. The rotation axis 218a of the take-up portion 218 is orthogonal to the traveling direction D2 of the base sheet 510. The width of the rotating shaft 218a along the Y axis is larger than the width of the sheet-shaped member 500.
 剥離シート巻取部218の外周面と支持部14の底面36との間には、シート状部材500が配設される。シート状部材500のうち、剥離シート520は、巻取部218の側を向き、ベースシート510は支持部14の側を向く。なお、シート状部材500が存在しない場合、巻取部218の外周面には、支持部14の底面36を接触可能である。 A sheet-like member 500 is arranged between the outer peripheral surface of the release sheet winding portion 218 and the bottom surface 36 of the support portion 14. Of the sheet-shaped members 500, the release sheet 520 faces the winding portion 218 side, and the base sheet 510 faces the support portion 14. When the sheet-shaped member 500 does not exist, the bottom surface 36 of the support portion 14 can be brought into contact with the outer peripheral surface of the take-up portion 218.
 剥離シート巻取部218には、パウダークラッチ232が接続されている。巻取部218の回転軸218aは、パウダークラッチ232に接続されている。パウダークラッチ232には、モータ234が接続されている。モータ234は、例えば定速モータを使用し得る。モータ234を駆動させたとき、パウダークラッチ232でモータ234の駆動軸をスリップさせながら、動力を巻取部218の回転軸218aに伝達する。巻取部218は、剥離シート520を巻き取る際、剥離シート520に対し、剥離シート520の破断応力以上の張力を負荷するのを防止する。 A powder clutch 232 is connected to the release sheet winding unit 218. The rotating shaft 218a of the take-up portion 218 is connected to the powder clutch 232. A motor 234 is connected to the powder clutch 232. As the motor 234, for example, a constant speed motor may be used. When the motor 234 is driven, power is transmitted to the rotating shaft 218a of the take-up unit 218 while the drive shaft of the motor 234 is slipped by the powder clutch 232. When winding the release sheet 520, the winding unit 218 prevents the release sheet 520 from being subjected to a tension equal to or greater than the breaking stress of the release sheet 520.

 支持部14は、剥離シート巻取部218のロール522の外周面に載置される。支持部14のエッジ(ベースシート510の裏面514を押さえた位置)34は、剥離シート巻取部218の上端に対して上方の位置にある。シート状部材500のベースシート510から剥離シート520を剥離する場合、支持部14と巻取部218のロール522の外周面との間には、シート状部材500(ベースシート510及び剥離シート520)が存在する。 The support portion 14 is placed on the outer peripheral surface of the roll 522 of the release sheet winding portion 218. The edge 34 of the support portion 14 (the position where the back surface 514 of the base sheet 510 is pressed) is located above the upper end of the release sheet winding portion 218. When the release sheet 520 is peeled from the base sheet 510 of the sheet-like member 500, the sheet-like member 500 (base sheet 510 and release sheet 520) is between the support portion 14 and the outer peripheral surface of the roll 522 of the take-up portion 218. Exists.
 引張部216は、シート状部材500の案内方向D1に対して、ベースシート510の進行方向D2を、支持部14のエッジ34で、鋭角αにする。鋭角αは0°よりも大きく、90°よりも小さい。引張部216は、支持部14により、ベースシート510の進行方向D2と、剥離シート520の進行方向D3とのなす角度を、支持部14で、90°以上の角度βにする。 The tension portion 216 sets the traveling direction D2 of the base sheet 510 with respect to the guiding direction D1 of the sheet-shaped member 500 at an acute angle α at the edge 34 of the support portion 14. The acute angle α is greater than 0 ° and less than 90 °. The tension portion 216 sets the angle formed by the support portion 14 between the traveling direction D2 of the base sheet 510 and the traveling direction D3 of the release sheet 520 at the support portion 14 at an angle β of 90 ° or more.
 ベースシート510は、支持部14のエッジ34で鋭角αに折り返される。ベースシート510は、剥離シート巻取部218の回転軸218aに巻き付けた剥離シート520のロール522の周方向から離れる方向に引っ張られる。ベースシート510の先端は、ローラ256,258、ダンサーローラ260、ニップローラ262を介してベースシート巻取部252に固定される。 The base sheet 510 is folded back at an acute angle α at the edge 34 of the support portion 14. The base sheet 510 is pulled in a direction away from the circumferential direction of the roll 522 of the release sheet 520 wound around the rotating shaft 218a of the release sheet winding portion 218. The tip of the base sheet 510 is fixed to the base sheet winding portion 252 via rollers 256, 258, dancer rollers 260, and nip rollers 262.
 支持部14と引張部216との間のベースシート510の経路のうち、支持部14に隣接する位置において、剥離シート520の移動方向(第3の方向)D3と、ベースシート510の進行方向(第2の方向)D2とのなす角度γは180°以上である。
 第3の方向D3に進行する剥離シート520が第2の方向D2に進行するベースシート510から剥離される際、剥離シート520は、ベースシート510を介して、ベースシート510の第2の方向D2に直交する方向に延びた支持部14のエッジ34に隣接し、剥離シート巻取部218の外周面又は剥離シート520のロール522の外周面に接する符号P1で示す位置から、剥離シート巻取部218の外周面又は剥離シート520のロール522の外周面の接線方向D31に移動する。符号P1は、剥離シート520がベースシート510から離される位置(剥離位置)である。符号P1で示す位置は、エッジ34の下端34bと剥離シート巻取部218の回転軸218aとを結ぶ仮想線L上、又は、仮想線Lよりも僅かに移動方向D3の方向に移動した位置(図7中の符号34bで示す位置に対して僅かに左側)とすることが好適である。接線方向D31は、剥離シート巻取部218の回転軸218aと符号P1とを結ぶ仮想線に対して直交する。このように、剥離シート520は、符号P1で示す位置で、ベースシート510に対して剥離される。このとき、支持部14は剥離シート520に触れないため、剥離シート520には、無理な負荷がかけられることが防止されている。
 符号P1で示す位置で剥離シート520が剥離したベースシート510は、支持部14の支持面32のエッジ34とは反対側の、連続面38との境界の符号P2で示す位置から、移動方向D21に向かって、接線方向D31に対して180°以上の角度γをもって進行する。すなわち、ベースシート510の第2の方向D2のうち、ベースシート510が支持部14の支持面32から離れる位置P2での移動方向D21は、接線方向D31に対して180度以上の角度γをなす。このように、支持部14に隣接する位置でのベースシート510の移動方向D21は、ベースシート510が支持部14の支持面32を離れる符号P2で示す位置と、後述するローラ256との位置関係で規定される。シート処理装置8の剥離装置210の稼働中、ベースシート510は、支持部14の支持面32に圧力を付加し続ける。このため、ベースシート510に対して張力が付加しなくなるのが防止される。符号P1,P2で示す位置は、あるZX平面上だけでなく、ベースシート510及び剥離シート520のY軸方向に沿う幅方向の1対の端面間の適宜の位置で同じである。剥離シート520の移動方向D3と、ベースシート510の進行方向D2とのなす角度γが180°以上である場合、ベースシート510は、支持部14のエッジ34及び支持面32に確実に密着しながら支持部14のエッジ34及び支持面32に対して摺動する。
 図7中、符号P2は、支持面32と連続面38との境界により規定される。支持面32と連続面38とが例えば滑らかな曲線となる場合、支持部14を離れる符号P2の位置は、支持面32又は連続面38に規定される。

The release sheet winding portion is adjacent to the edge 34 of the support portion 14 extending in the direction orthogonal to the above, and is in contact with the outer peripheral surface of the release sheet winding portion 218 or the outer peripheral surface of the roll 522 of the release sheet 520. It moves in the tangential direction D31 of the outer peripheral surface of 218 or the outer peripheral surface of the roll 522 of the release sheet 520. Reference numeral P1 is a position (peeling position) where the release sheet 520 is separated from the base sheet 510. The position indicated by reference numeral P1 is a position on the virtual line L connecting the lower end 34b of the edge 34 and the rotation axis 218a of the release sheet winding portion 218, or a position slightly moved in the moving direction D3 from the virtual line L ( It is preferably slightly to the left of the position indicated by reference numeral 34b in FIG. 7. The tangential direction D31 is orthogonal to the imaginary line connecting the rotation axis 218a of the release sheet winding portion 218 and the reference numeral P1. In this way, the release sheet 520 is peeled off from the base sheet 510 at the position indicated by the reference numeral P1. At this time, since the support portion 14 does not touch the release sheet 520, it is prevented that an unreasonable load is applied to the release sheet 520.
The base sheet 510 from which the release sheet 520 has been peeled off at the position indicated by reference numeral P1 is moved in the moving direction D21 from the position indicated by reference numeral P2 at the boundary with the continuous surface 38 on the side opposite to the edge 34 of the support surface 32 of the support portion 14. At an angle γ of 180 ° or more with respect to the tangential direction D31. That is, in the second direction D2 of the base sheet 510, the moving direction D21 at the position P2 where the base sheet 510 is separated from the support surface 32 of the support portion 14 forms an angle γ of 180 degrees or more with respect to the tangential direction D31. .. As described above, the moving direction D21 of the base sheet 510 at the position adjacent to the support portion 14 is the positional relationship between the position indicated by the reference numeral P2 at which the base sheet 510 leaves the support surface 32 of the support portion 14 and the roller 256 described later. Is specified in. While the peeling device 210 of the sheet processing device 8 is in operation, the base sheet 510 continues to apply pressure to the support surface 32 of the support portion 14. Therefore, it is possible to prevent tension from being applied to the base sheet 510. The positions indicated by reference numerals P1 and P2 are the same not only on a certain ZX plane but also at appropriate positions between a pair of end faces in the width direction along the Y-axis direction of the base sheet 510 and the release sheet 520. When the angle γ formed by the moving direction D3 of the release sheet 520 and the traveling direction D2 of the base sheet 510 is 180 ° or more, the base sheet 510 is securely adhered to the edge 34 and the support surface 32 of the support portion 14. It slides on the edge 34 and the support surface 32 of the support portion 14.
In FIG. 7, reference numeral P2 is defined by the boundary between the support surface 32 and the continuous surface 38. When the support surface 32 and the continuous surface 38 form a smooth curve, for example, the position of the reference numeral P2 away from the support portion 14 is defined by the support surface 32 or the continuous surface 38.

Assuming that the thickness of the support portion 14 (thickness of the edge 34 and the continuous surface 38) is ignored, the lower end of the roller 256 is below the upper end of the release sheet winding portion 218. In this case, the angle γ is defined. It is more preferable that the rotation axis (central axis) of the roller 256 is below the rotation axis (central axis) 218a of the release sheet winding portion 218.

 支持部14の底面36と、剥離シート520を巻き付けたロール522の外周面との間に、シート状部材500を配置する。このとき、支持部14の底面36を、シート状部材500のベースシート510の裏面514に当接させる。 The sheet-like member 500 is arranged between the bottom surface 36 of the support portion 14 and the outer peripheral surface of the roll 522 around which the release sheet 520 is wound. At this time, the bottom surface 36 of the support portion 14 is brought into contact with the back surface 514 of the base sheet 510 of the sheet-like member 500.
 この状態で、ベースシート510を支持部14のエッジ34で鋭角αに折り返し、剥離シート巻取部218の回転軸218aに巻き付けた剥離シート520のロール522から離れる方向にベースシート510を引っ張る。ベースシート510の先端を、ローラ256,258、ダンサーローラ260、ニップローラ262を介してベースシート巻取部252に固定する。 In this state, the base sheet 510 is folded back at an acute angle α at the edge 34 of the support portion 14, and the base sheet 510 is pulled in a direction away from the roll 522 of the release sheet 520 wound around the rotation shaft 218a of the release sheet winding portion 218. The tip of the base sheet 510 is fixed to the base sheet winding portion 252 via rollers 256, 258, dancer rollers 260, and nip rollers 262.
 この状態で、シート処理装置8のプロセッサPは、各モータ228,234,254,264、及びパウダークラッチ232を駆動させる。プロセッサPは、各センサS1-S6で検知しながら、検知した信号に基づいて、各モータ228,234,254,264、及びパウダークラッチ232を制御する。 In this state, the processor P of the seat processing device 8 drives each of the motors 228, 234, 254, 264, and the powder clutch 232. The processor P controls each of the motors 228, 234, 254, 264, and the powder clutch 232 based on the detected signals while detecting by the sensors S1-S6.
 剥離装置210のプロセッサPは、モータ228を駆動し、ニップローラ226を回転させる。ニップローラ226は例えば20m/min以下でシート状部材500を所定の案内方向(X軸方向)D1に案内する。ニップローラ226の回転速度により、剥離装置210全体の処理速度を決定する。巻出部222は、シート状部材500が所定の案内方向D1に案内されるのに伴って、従動して回転する。 The processor P of the peeling device 210 drives the motor 228 to rotate the nip roller 226. The nip roller 226 guides the sheet-shaped member 500 in a predetermined guide direction (X-axis direction) D1 at, for example, 20 m / min or less. The processing speed of the entire peeling device 210 is determined by the rotation speed of the nip roller 226. The unwinding portion 222 is driven and rotated as the sheet-shaped member 500 is guided in the predetermined guiding direction D1.
 モータ254を駆動させて巻取部252の回転軸252aを回転させると、ベースシート510が巻取部252の回転軸252aの外周に巻き付いていく。巻取部252は、ベースシート510をトルクモータ254により一定トルクで巻き取る。このため、巻取部252は、ベースシート510に一定の張力を付加する。ベースシート巻取部252のロール516の半径r1は次第に大きくなる。巻出部222のロール502の半径r0は次第に小さくなる。モータ228,254の駆動開始は同時でもよく、ベースシート510のたるみに応じて、モータ228をトルクモータ254に対して遅れて駆動させてもよい。 When the motor 254 is driven to rotate the rotating shaft 252a of the winding unit 252, the base sheet 510 winds around the outer circumference of the rotating shaft 252a of the winding unit 252. The take-up unit 252 winds the base sheet 510 with a constant torque by the torque motor 254. Therefore, the winding unit 252 applies a constant tension to the base sheet 510. The radius r1 of the roll 516 of the base sheet winding portion 252 gradually increases. The radius r0 of the roll 502 of the unwinding portion 222 gradually becomes smaller. The driving of the motors 228 and 254 may be started at the same time, or the motor 228 may be driven later than the torque motor 254 according to the slack of the base sheet 510.
 第6のセンサS6でダンサーローラ260の位置を検知する。第6のセンサS6の検知信号がプロセッサPに入力されると、プロセッサPはモータ264を制御して、ニップローラ262の回転速度を増速又は減速させる。このため、プロセッサPは、ダンサーローラ260の位置に応じてニップローラ262の回転数を加減速し、ダンサーローラ260の位置を所定範囲に保つ。ダンサーローラ260は、上下動することにより、ベースシート510に対する張力を一定に維持する。 The position of the dancer roller 260 is detected by the sixth sensor S6. When the detection signal of the sixth sensor S6 is input to the processor P, the processor P controls the motor 264 to increase or decrease the rotation speed of the nip roller 262. Therefore, the processor P accelerates / decelerates the rotation speed of the nip roller 262 according to the position of the dancer roller 260, and keeps the position of the dancer roller 260 within a predetermined range. The dancer roller 260 moves up and down to maintain a constant tension on the base sheet 510.
 支持部14とダンサーローラ260との間の第5のセンサS5aは、ベースシート510上の剥離シート520の存在を検知する。第5のセンサS5aがベースシート510に対して剥離シート520が剥離されていないことを検知し、その信号がプロセッサPに入力された場合、プロセッサPは、シート処理装置8の動作を停止させる。または、プロセッサPは、適宜のスピーカから警告を発するだけでもよい。 The fifth sensor S5a between the support portion 14 and the dancer roller 260 detects the presence of the release sheet 520 on the base sheet 510. When the fifth sensor S5a detects that the release sheet 520 has not been peeled from the base sheet 510 and the signal is input to the processor P, the processor P stops the operation of the sheet processing device 8. Alternatively, the processor P may only issue a warning from an appropriate speaker.
 第5のセンサS5bは、ベースシート510の破断を検知する。第5のセンサS5bでベースシート510に破断が生じたことを検知し、その信号がプロセッサPに入力された場合、プロセッサPは、シート処理装置8の動作を停止させる。または、プロセッサPは、適宜のスピーカから警告音を発するだけでもよい。 The fifth sensor S5b detects the breakage of the base sheet 510. When the fifth sensor S5b detects that the base sheet 510 has broken and the signal is input to the processor P, the processor P stops the operation of the sheet processing device 8. Alternatively, the processor P may only emit a warning sound from an appropriate speaker.
 ニップローラ226の近傍の第3のセンサS3は、超音波によりシート状部材500の幅方向の端面(エッジ)を検知可能である。プロセッサPは、シート状部材500の幅方向の端面(エッジ)を検知することで、シート状部材500の走行時の蛇行状態を認識可能である。そして、第3のセンサS3の検知結果に基づいて、プロセッサPは、例えば第1実施形態で説明した調整機構24で、シート状部材500の走行位置を制御する。 The third sensor S3 in the vicinity of the nip roller 226 can detect the end face (edge) of the sheet-like member 500 in the width direction by ultrasonic waves. The processor P can recognize the meandering state of the sheet-shaped member 500 during traveling by detecting the end surface (edge) of the sheet-shaped member 500 in the width direction. Then, based on the detection result of the third sensor S3, the processor P controls the traveling position of the sheet-shaped member 500 by, for example, the adjustment mechanism 24 described in the first embodiment.
 巻出部222とニップローラ226との間のカッタ600(図1参照)は、シート状部材500のベースシート510及び剥離シート520の端部近傍を切断する。このため、ニップローラ226を回転させ、シート状部材500が所定の案内方向D1に案内されると、カッタ600により、シート状部材500のベースシート510及び剥離シート520の端部近傍が切断される。なお、第3のセンサS3による検知結果、及び/又は、第1実施形態で説明した調整機構24により、カッタ600によるシート状部材500の端部の切断位置が安定した状態を維持する。 The cutter 600 (see FIG. 1) between the unwinding portion 222 and the nip roller 226 cuts the vicinity of the ends of the base sheet 510 and the release sheet 520 of the sheet-like member 500. Therefore, when the nip roller 226 is rotated and the sheet-shaped member 500 is guided in the predetermined guide direction D1, the cutter 600 cuts the vicinity of the ends of the base sheet 510 and the release sheet 520 of the sheet-shaped member 500. The detection result by the third sensor S3 and / or the adjustment mechanism 24 described in the first embodiment keeps the cutting position of the end portion of the sheet-shaped member 500 by the cutter 600 stable.
 第4のセンサS4は、剥離シート巻取部218の巻取径を検知する。プロセッサPは、巻取部218の巻取径に応じて、パウダークラッチ232のスリップ率を制御する。または、プロセッサPは、剥離シート巻取部218の巻取径に応じて、単位時間あたりの剥離シート巻取部218の回転軸218aの回転数を制御してもよい。 The fourth sensor S4 detects the winding diameter of the release sheet winding unit 218. The processor P controls the slip ratio of the powder clutch 232 according to the winding diameter of the winding unit 218. Alternatively, the processor P may control the rotation speed of the rotation shaft 218a of the release sheet winding unit 218 per unit time according to the winding diameter of the release sheet winding unit 218.
 巻取部252の回転により、シート状部材500のベースシート510の裏面514は、支持部14のエッジ34の下端34b、及び、底面36のうち下端34bの近傍に密着しながら、支持部14に対して摺動する。ベースシート510は、支持部14のエッジ34で折り返される。ベースシート510の裏面514は、支持部14の支持面32に密着した状態で、引っ張られている。 Due to the rotation of the take-up portion 252, the back surface 514 of the base sheet 510 of the sheet-like member 500 is brought into the support portion 14 while being in close contact with the lower end 34b of the edge 34 of the support portion 14 and the vicinity of the lower end 34b of the bottom surface 36. It slides against it. The base sheet 510 is folded back at the edge 34 of the support portion 14. The back surface 514 of the base sheet 510 is pulled in close contact with the support surface 32 of the support portion 14.
 エッジ34の下端34bの位置、特に、符号P1で示す、シート状部材500のベースシート510に対する剥離シート520の剥離位置において、シート状部材500がロール522の外周に沿う移動方向D1に移動する速度と、剥離シート520が剥離したベースシート510が移動方向D2に移動する速度と、ベースシート510から剥離した剥離シート520がロール522の外周に沿う移動方向D3(接線方向D31)に移動する速度とは、一致する。剥離シート520は、エッジ34の下端34bでベースシート510から剥離する。剥離シート520は、剥離シート巻取部218の回転軸218aの回転により、剥離シート巻取部218の外周又はロール522の外周に巻き付けられていく。 The speed at which the sheet-shaped member 500 moves in the moving direction D1 along the outer periphery of the roll 522 at the position of the lower end 34b of the edge 34, particularly at the peeling position of the peeling sheet 520 with respect to the base sheet 510 of the sheet-shaped member 500 indicated by reference numeral P1. The speed at which the base sheet 510 peeled from the release sheet 520 moves in the moving direction D2 and the speed at which the peeling sheet 520 peeled from the base sheet 510 moves in the moving direction D3 (tangential direction D31) along the outer periphery of the roll 522. Match. The release sheet 520 is peeled from the base sheet 510 at the lower end 34b of the edge 34. The release sheet 520 is wound around the outer circumference of the release sheet winding portion 218 or the outer circumference of the roll 522 by the rotation of the rotation shaft 218a of the release sheet winding portion 218.
 支持部14のエッジ34の下端34bで剥離シート520が剥離したベースシート510は、裏面514が支持部14の支持面32に密着しながら、巻取部252に向かって搬送される。 The base sheet 510 from which the release sheet 520 has been peeled off at the lower end 34b of the edge 34 of the support portion 14 is conveyed toward the take-up portion 252 while the back surface 514 is in close contact with the support surface 32 of the support portion 14.
 支持部14の支持面32に密着したベースシート510の裏面514は、支持部14の符号P2で示す位置で、符号P1で示す位置の接線方向D31に対して180度以上の角度γをなす移動方向D21に向けられて移動される。このため、支持部14のエッジ34以降のベースシート510の走行方向D2は、支持部14の回転軸42aを回転中心として、支持部14をロール522の表面に押しつける方向に、常に回転トルクを発生するように規制されている。ベースシート510の走行方向D2(移動方向D21)の移動による支持部14への回転トルク発生のために、ダンサーローラ260の前に固定された走行方向D2のローラ256,258が配置され、走行方向D2(移動方向D21)を規制する。ローラ256,258を用いない場合、ダンサーローラ260の上端位置を剥離シート巻取部218の回転軸218aよりも下側に規制してもよい。例えば、走行方向のローラ(固定)256の上面が剥離シート巻取部218の回転軸218aの高さを超えないように設置することで実現できる。 The back surface 514 of the base sheet 510, which is in close contact with the support surface 32 of the support portion 14, moves at an angle γ of 180 degrees or more with respect to the tangential direction D31 of the position indicated by the reference numeral P1 at the position indicated by the reference numeral P2 of the support portion 14. It is moved toward direction D21. Therefore, the traveling direction D2 of the base sheet 510 after the edge 34 of the support portion 14 always generates a rotational torque in the direction of pressing the support portion 14 against the surface of the roll 522 with the rotation shaft 42a of the support portion 14 as the center of rotation. It is regulated to do. Rollers 256, 258 of the traveling direction D2 fixed in front of the dancer roller 260 are arranged in front of the dancer roller 260 to generate rotational torque to the support portion 14 due to the movement of the traveling direction D2 (moving direction D21) of the base sheet 510, and the traveling direction. D2 (movement direction D21) is regulated. When the rollers 256 and 258 are not used, the upper end position of the dancer roller 260 may be restricted below the rotation shaft 218a of the release sheet winding portion 218. For example, it can be realized by installing the upper surface of the roller (fixed) 256 in the traveling direction so as not to exceed the height of the rotating shaft 218a of the release sheet winding portion 218.
 ベースシート510の移動速度はニップローラ226の回転により一定に保たれている。ベースシート510の張力はダンサーローラ260により一定状態に制御されている。 The moving speed of the base sheet 510 is kept constant by the rotation of the nip roller 226. The tension of the base sheet 510 is controlled to a constant state by the dancer roller 260.
 剥離シート巻取部218の回転速度は、剥離シート520に負荷をかけない状態に調整されている。 The rotation speed of the release sheet winding unit 218 is adjusted so that no load is applied to the release sheet 520.
 モータ234は、パウダークラッチ232を介して剥離シート巻取部218を所定方向(図5中の反時計回り方向)に回転させ、剥離シート520を剥離シート巻取部218に巻き取らせる。剥離シート巻取部218のロール522の半径r2は次第に大きくなる。上述したように、剥離シート520は破断及び/又はクラックが生じやすい。パウダークラッチ232は、シート状部材500の速度に合わせてモータ234の回転軸を巻取部218に対して適宜にスリップさせる。具体的には、ロール522の半径r2の変化に合わせてプロセッサPは、パウダークラッチ232を制御し、シート状部材500の速度に合わせてモータ234の回転軸のスリップ率を調整する。プロセッサPは、巻取部218の回転軸218aの回転によるロール522の外周の速度と、剥離直前のシート状部材500の剥離シート520の速度とを一致させている。すなわち、ベースシート510の表面512に張り付いた剥離シート520と、ベースシート510から剥離した剥離シート520との速度差をより小さくしている。 The motor 234 rotates the release sheet winding section 218 in a predetermined direction (counterclockwise direction in FIG. 5) via the powder clutch 232 to wind the release sheet 520 around the release sheet winding section 218. The radius r2 of the roll 522 of the release sheet winding portion 218 gradually increases. As described above, the release sheet 520 is prone to breakage and / or cracking. The powder clutch 232 appropriately slips the rotating shaft of the motor 234 with respect to the winding portion 218 according to the speed of the sheet-shaped member 500. Specifically, the processor P controls the powder clutch 232 according to the change in the radius r2 of the roll 522, and adjusts the slip ratio of the rotation shaft of the motor 234 according to the speed of the sheet-shaped member 500. The processor P matches the speed of the outer circumference of the roll 522 due to the rotation of the rotating shaft 218a of the winding unit 218 with the speed of the peeling sheet 520 of the sheet-like member 500 immediately before peeling. That is, the speed difference between the release sheet 520 attached to the surface 512 of the base sheet 510 and the release sheet 520 peeled from the base sheet 510 is made smaller.
 このように、剥離シート巻取部218の回転軸218aのロール522の半径r2が大きくなるにつれて、パウダークラッチ232のスリップ率を調整し、シート状部材500の移動速度、ベースシート510の移動速度、シート状部材500のベースシート510から剥離させた剥離シート520の移動速度が支持部14のエッジ34で一致又は略一致した状態を維持する。 In this way, as the radius r2 of the roll 522 of the rotating shaft 218a of the release sheet winding portion 218 increases, the slip ratio of the powder clutch 232 is adjusted, and the moving speed of the sheet-shaped member 500, the moving speed of the base sheet 510, and so on. The moving speed of the release sheet 520 peeled from the base sheet 510 of the sheet-like member 500 is maintained at the same or substantially the same at the edge 34 of the support portion 14.
 シート状部材500の移動速度、ベースシート510の移動速度、シート状部材500のベースシート510から剥離させた剥離シート520の移動速度をエッジ34で一致させるために、剥離シート520のロール522の外周にシート状部材500を半周巻き付けている。仮に、図7で支持部14の底面36に接した方向からシート状部材500を供給すると、剥離シート520のロール522の半径r2が変化するにつれてスリップ率の制御の精度が重要となる。少しのズレでも剥離シート520の破断を招くことが容易に想像される。シート状部材500を剥離シート520のロール522に半周巻き付けていることで、ベースシート510の表面512と剥離シート520との摩擦により、スリップ率が自律的に制御される。摩擦力は、パウダークラッチ232をより滑らせ、熱に変換されて放出される。 In order to match the moving speed of the sheet-shaped member 500, the moving speed of the base sheet 510, and the moving speed of the peeling sheet 520 peeled from the base sheet 510 of the sheet-shaped member 500 at the edge 34, the outer circumference of the roll 522 of the peeling sheet 520 is matched. A sheet-shaped member 500 is wound around the surface halfway. If the sheet-shaped member 500 is supplied from the direction in contact with the bottom surface 36 of the support portion 14 in FIG. 7, the accuracy of controlling the slip ratio becomes important as the radius r2 of the roll 522 of the release sheet 520 changes. It is easily imagined that even a slight deviation will cause the release sheet 520 to break. By winding the sheet-shaped member 500 around the roll 522 of the release sheet 520 half a circumference, the slip ratio is autonomously controlled by the friction between the surface 512 of the base sheet 510 and the release sheet 520. The frictional force causes the powder clutch 232 to slide more and is converted into heat and released.
 このため、剥離装置210を用いて、ベースシート510から剥離シート520を剥離させる際に、剥離シート520に破断及び/又はクラックが生じるような負荷がかけられるのが防止される。 Therefore, when the release sheet 520 is peeled from the base sheet 510 by using the release device 210, it is possible to prevent the release sheet 520 from being subjected to a load that causes breakage and / or cracks.
 剥離シート520のロール522のうち、巻取部218の回転軸218aに近接する面及び離隔する面が、自身により順次覆われていく。このため、剥離シート520のロール522は、外周側よりも内周側の乾燥を抑制することができる。 Of the roll 522 of the release sheet 520, the surface of the take-up portion 218 that is close to and separated from the rotation shaft 218a is sequentially covered by itself. Therefore, the roll 522 of the release sheet 520 can suppress drying on the inner peripheral side rather than the outer peripheral side.
 支持部14は、シート状部材500を挟んで、剥離シート巻取部218のロール522の外周に重力等により、載置されている。支持部14は、巻取部218の回転軸218aに剥離シート520が巻き取られ、ロール522の外径が大きくなるにつれて、中心軸42aの軸回りに回動し、回転軸218aの回転中心から離される。巻出部222のロール502の巻径(半径r0)は次第に小さくなる。 The support portion 14 is placed on the outer periphery of the roll 522 of the release sheet winding portion 218 by gravity or the like with the sheet-shaped member 500 sandwiched therein. The support portion 14 is wound around the rotating shaft 218a of the winding portion 218, and as the outer diameter of the roll 522 increases, the support portion 14 rotates around the axis of the central shaft 42a and from the rotation center of the rotating shaft 218a. Be separated. The winding diameter (radius r0) of the roll 502 of the unwinding portion 222 gradually becomes smaller.
 第2のセンサS2で剥離シート520の終端を検知した場合、プロセッサPに信号が入力され、プロセッサPは、適宜のスピーカから警告音を発し、その後、各モータ228,234,254,264の動作を停止させる。このため、第2のセンサS2で剥離シート520の終端を検知した場合、プロセッサPは、ユーザに、剥離シート520の終端が第2のセンサS2の検知位置を通過したことを認識させるように、適宜のスピーカから警告音を発する。 When the end of the release sheet 520 is detected by the second sensor S2, a signal is input to the processor P, the processor P emits a warning sound from an appropriate speaker, and then the operations of the respective motors 228, 234, 254, 264 are performed. To stop. Therefore, when the end of the release sheet 520 is detected by the second sensor S2, the processor P makes the user recognize that the end of the release sheet 520 has passed the detection position of the second sensor S2. A warning sound is emitted from an appropriate speaker.
 一方、第2のセンサS2で、ベースシート510に破断及び/又はクラックがあることを検知した場合、プロセッサPは、直ちにシート処理装置8の動作を停止させる。 On the other hand, when the second sensor S2 detects that the base sheet 510 has a break and / or a crack, the processor P immediately stops the operation of the sheet processing device 8.
 第1のセンサS1でシート状部材500の終端又はその近傍を検知した場合、プロセッサPに信号が入力され、プロセッサPは、ユーザにシート状部材500の終端又はその近傍を知らせるべく適宜のスピーカから警告音を発し、又は停止する。プロセッサPは、ベースシート510の終端をベースシート巻取部252で巻き終えた後、シート処理装置8の動作を停止させる。なお、ベースシート巻取部252と剥離シート巻取部218の位置関係により、ベースシート510の終端を巻き終える前に、剥離シート520の終端を巻き終えている。 When the first sensor S1 detects the end of the sheet-shaped member 500 or its vicinity, a signal is input to the processor P, and the processor P notifies the user of the end of the sheet-shaped member 500 or its vicinity from an appropriate speaker. Sounds a warning or stops. The processor P stops the operation of the sheet processing device 8 after the end of the base sheet 510 is wound by the base sheet winding unit 252. Due to the positional relationship between the base sheet winding section 252 and the release sheet winding section 218, the end of the release sheet 520 is wound before the end of the base sheet 510 is finished.
 本実施形態では、剥離装置210にパウダークラッチ232を用いる例について説明した。剥離装置210は、パウダークラッチ232の代わりに、流体クラッチを用いてもよい。 In the present embodiment, an example in which the powder clutch 232 is used for the peeling device 210 has been described. The release device 210 may use a fluid clutch instead of the powder clutch 232.
 以上説明したように、本実施形態に係る剥離装置210を含むシート処理装置8は、以下のことが言える。 As described above, the sheet processing device 8 including the peeling device 210 according to the present embodiment can be said to be as follows.
 本実施形態に係る剥離装置210によれば、剥離シート(機能シート)520をベースシート510から剥離可能な剥離装置210、シート処理装置8、及び、剥離方法が提供される。 According to the peeling device 210 according to the present embodiment, the peeling device 210, the sheet processing device 8, and the peeling method capable of peeling the peeling sheet (functional sheet) 520 from the base sheet 510 are provided.
 剥離装置210は、シート状部材500の裏面514を支持部14に接触させた直後、ベースシート510の移動方向D2を鋭角αなど、大きく変え、剥離シート520の移動方向D3と別方向に送っている。このため、剥離装置210は、剥離シート520に触れず、ベースシート510に対して剥離シート520を剥離させることができる。このとき、剥離シート520自体に負荷をかけていない。このため、剥離装置210を用いることで、剥離シート520にクラック及び/又は破断が生じるのを抑制することができる。 Immediately after the back surface 514 of the sheet-like member 500 is brought into contact with the support portion 14, the peeling device 210 significantly changes the moving direction D2 of the base sheet 510 to an acute angle α or the like, and sends the peeling sheet 520 in a direction different from the moving direction D3. There is. Therefore, the peeling device 210 can peel the peeling sheet 520 against the base sheet 510 without touching the peeling sheet 520. At this time, no load is applied to the release sheet 520 itself. Therefore, by using the peeling device 210, it is possible to suppress the occurrence of cracks and / or breakage in the peeling sheet 520.
 シート処理装置8は、シート状部材500のベースシート510から剥離シート520を剥離させるとともに、剥離シート520のロール522を形成する。このため、例えば数十メートル以上となるような剥離シート520の保管及び輸送が容易となる。剥離シート520のロール522を形成する場合、剥離シート520は、ロール522の半径r2の方向に多数枚重ねられる。このため、剥離シート520は、巻取部218の回転軸218aに近接する面及び離隔する面が、自身により覆われる。このため、シート処理装置8は、ロール522を形成すると、剥離シート520の乾燥を抑制することができる。 The sheet processing device 8 peels the release sheet 520 from the base sheet 510 of the sheet-like member 500 and forms a roll 522 of the release sheet 520. Therefore, for example, the release sheet 520 having a length of several tens of meters or more can be easily stored and transported. When forming the roll 522 of the release sheet 520, a large number of release sheets 520 are stacked in the direction of the radius r2 of the roll 522. Therefore, in the release sheet 520, the surface of the take-up portion 218 that is close to and separated from the rotation shaft 218a is covered by itself. Therefore, when the roll 522 is formed, the sheet processing device 8 can suppress the drying of the release sheet 520.
